Wow! ... You're painting ALL elves with a pretty broad brush here Entori and you seem to be picking only what you wish from many of the sources. Example:
"Elves have a great stigma for half elves.. they call them "breeds" or bend an ear at them is great insult." ... this is a gross exageration actually. While some elves do certainly feel this way, not all or even the majority of them do. Not all half elves are the product of youthful indiscetions as you'd lead us to believe either. Many elves actually envy humans and the other "young" races. They envy their passions and ambitions and overall zest for life. Half elves do carry stigmas, but it will often depend where they were born and raised as to what the stigma is. Most elves would feel pity for their half-blood kin due to their shortened lifespan, but rarely more than that. Moon, Wood and Wild Elves are generally far more accepting of half elves than Sun Elves are though. Temperaments and views amongst elves also vary from city to city and region to region. Elves living in the harsher northlands of faerun are more open to half elves and other races.
So .... if you're an elf from Evermeet ... then most of what you've posted I can't refute. But, you never mention that. You repeatedly use the term "Elves" as if the view you put forth is wrote for all. It's not.
As for the shrine to Sylvanus in Evereska ... regardless of the source (Candlekeep in this case), there are elven followers of Sylvanus in Faerun. They know of the Seldarine and do not deny their existance, but they do not always follow the Seldarine. These followers of Sylvanus are usually Wild Elves and the odd Wood Elf. They believe Sylvanus is the embodiment of the old totem spirits of the Yuirwood that their ancestors worshiped. Though the different FR sources vary, many suggest that the old gods/spirits were replaced by both the Seldarine and Sylvanus. If you look up Sylvanus in the FR Faiths and Pantheons you'll notice the following as well.
Worshipers: Druids, woodsmen, wood elvesNow some snippets from FR Races of Faerun.
Moon Elves, Relations with Other Races:
Of the elven subraces, moon elves are the most tolerant of nonelves.
They travel extensively, and a moon elf can expect to
interact with hundreds of different races throughout her life.
Moon elves find the diversity of Faerûn’s races to be intoxicating
and forever surprising, and they especially value theinsights of other races because they often think of things no elfwould ever consider. This openness and willingness to acceptnew ideas is regarded as foolish and dangerous by other elves, so ironically their own kin often give moon elves the coolest receptions.
Despite their open minds, moon elves have little patience or
interest in the various evil beings, and they hold orcs and gnolls
in particular contempt. They avoid regions where such cultures
hold sway, although moon elf adventurers often infiltrate these areas to spy on them. The moon elves share with the other elven
subraces a hatred and loathing for the drow.
** Does that sound like the paranoid xenophobicic uptight elves you've portrayed?
Moon Elf Deities:
Moon elves worship the Seldarine. A moon elf identifies with all
the elven deities, but usually chooses one as a patron deity above the others. Unlike their sun elf cousins, many moon elves worship the elven deity Angharradh, who they believe to be a melding of the three goddesses Sehanine, Aerdrie Faenya, and Hanali Celanil. The moon elves view her as equal in power to Corellon Larethian, who is often regulated to the status of a consort. Moon elf religious ceremonies are exuberant, joyful, and loud. Even deeply religious moon elves recognize that some ceremonies and festivals are simply excuses for revelry.
**Whoa ... elves that put other gods above or equal to Corellon .. OMG!
Sun Elves, Relations with Other Races
The sun elves feel affection for the moon elves, although this
affection is often unintentionally patronizing. They fear that
their moon elf cousins are too flighty and irreverent, and they
strive to help them return to the proper elven path with stern
lectures and fatherly advice. They admire the wood elves and
feel that they embody the elven spirit of nature. Relations are
good between sun elf and wood elf, although the reclusive nature
of the wood elves makes direct contact rare. Sun elves are a bit
puzzled by the wild elves, and hope one day to civilize them.
Aquatic elves are thought of as near-equals, and the sun elves
believe that their water-breathing kin were placed in the world
to bring to the seas what the sun elves bring to the lands above.
The sun elves deeply regret the sufferings of the avariels, and
occasionally send out explorers to seek out avariel aeries and
offer them a place on Evermeet.
Sun elf prejudice toward other races (humans in particular)
can be quite severe. Many sun elves won’t even deign to speak
to a human and would rather leave a dying man to meet his fate
than to save him. This attitude is somewhat understandable,
given the way humans have historically treated the sun elves
and their lands, but it wins the sun elves few friends among their
human neighbors.
If there is one race that the sun elves hold in absolute contempt,
it is the drow. They view the dark elves as abominations
and insults to the Seldarine, and often attack these hated enemies on sight. As word of the drow invasion of Cormanthor
begins to spread through Evermeet, it is likely that more and
more sun elves will return to the mainland, if only to bring war
to the drow and force them from the ruins of what sun elves
still consider their lands.
** Now we know where you get your information
The D@#$ed haughty, arrogant Sun Elves:P
5th paragraph of the general info on Sun Elves:
Of all the elven subraces, sun elves are the most arrogant and
haughty—even more so than the avariels, whose haughtiness is
rooted in pity for the landbound races. Sun elves believe that
they are the true elven race, the builders and the leaders of the
elven realms, and that the other elven subraces fail to live up to
the solemnity and dignity of their ancient stock.
**Sounds just like most of your posts.
Wild Elf Deities
The wild elves worship the Seldarine, in particular Rillifane
Rallathil, but this worship does not approach the regimented,
organized structure of the other elven subraces. Rather, the
green elves worship individually when the urge takes them. They
commune constantly with a pantheon of nature spirits, each
representing an archetypal member of an animal or natural
phenomenon.
** Some FR sources hint at Rillifane and Sylvanus as being the same being also.**
Wild Elves, Relations with Other Races:
The green elves do not seek out relations with others, and they
do their best to remain unseen and unknown. Nevertheless, wild
elves have been known to interact with adventurers, explorers,
and lost travelers. Usually, these people are captured, their memories magically erased, and then let go somewhere far from the tribal lands. Rarely, the elves allow a wanderer to visit their
camp, usually in times of dire peril when they are forced to call
upon outside aid. Those who manage to impress and even
befriend a tribe of wild elves find that their friendship is strong
and loyal, and such individuals are often gifted with wild elf
tattoos or spirit animals.
**Reclusive though not the haughty creatures many think all elves are.
Wood Elf Deities
Wood elves worship the Seldarine, but they hold a special respect
and reverence for the ancient forest powers of Faerûn, Silvanus
and Mielikki. Among the Seldarine, the wood elves hold a particular reverence for Solonor Thelandira, the Great Archer, and
Rillifane Rallathil, the Leaflord. Solonor, as the deity of archery
and the hunt, is viewed as the special patron of the wood elves,
and before battle a wood elf will often invoke his name.
**Noooooo! More elves that don't worship JUST the Seldarine ... *feints*
Wood Elves, Relations with Other Races:
In the five hundred years since the fall of Eaerlann, the wood
elves have been forgotten by most of the other peoples of
Faerûn. Only those humans and dwarves native to the North
and familiar with the borders of the High Forest have seen
copper elves, and even then, they most likely met a solitary
hunter or ranger. While the wood elves shelter deep inside forbidding forests and are therefore inaccessible to their neighbors, they are ironically among the more compassionate and understanding of the elven subraces. Like the moon elves, they accept the power of humankind and seek to live alongside their human neighbors and guide their expansion instead of seeking ways to deter or intimidate the human lands.
Wood elves have a long history of cooperation with the shield
dwarves, whose realm of Ammarindar stood alongside their own
realm of Eaerlann for many centuries in the vale of the Delimbiyr
River. By extension, they look favorably on most other dwarves, too. Gnomes and halflings are both greeted as friends and potential allies. On the other hand, the wood elves have a cold place in their hearts for creatures such as orcs and gnolls, who bring axes, fire, and slaughter to the forests the wood elves have sworn to preserve.
**Now why would they snub half elves if as stated they seek to live in harmony with humans?
Not to pick ONLY on you Entori, but your posts have been the dominate ones I'm addressing. If you replace Elf/Elves with Sun Elf/Elves in 99% of your posts then I'd have no issue. But, as I've shown ... from the sources ... MOST elves are not as you portray them.
