From what I have read, it seems sorceror's are accepted in Calimshan. Many leave Amn and even Tethyr heading south for Calimshan where they can be paid very well for thier serves to some pasha. I think they are consider equals of the wizards of Calimshan. The local sorcerors normally are apt at fire spells due to being of efreeti linage.
This is incorrect. Magic is respected and quite common in Calimshan, yes, and wizards are respected. (In Amn all arcane magic is commonly feared and distrusted.) This is limited to wizardry moreso than sorcery because sorcerors are shunned in Calimshan. They are considered to be genie-blooded. The Calim Caliphates were ruled by genies for 1,000 years before a form of Old High Magic was used to bind the genies Calim and Memnon to the sands and air, where they still struggle against each other to this day in what has become the Calim Desert. Both the Djinni and the Efreeti had other genies allied with them. Most of those were defeated or fled but the Calishiites still shun those who are considered to have genie-blood.
Of course that's not in direct response to Henny's post. I will say that I have never read that sorcerors are new to Faerun. Time of Troubles was 1358, current time is 1372. That means the oldest sorceror would be 14 so I doubt the accuracy of your source.
As for the interloper race in their gene pool, that is a prevailing theory, and clearly in some cases (Dragon Disciples) it is true.
Here is what the Forgotten Realms Campaign Setting says about sorcerors (pg. 27):
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
SorcerorSorcerors are (along with wizards) the foremost practicioners of what Faerunians refer to as the Art, the study and application of arcane magic. The common folk of Faerun see little difference between the rigorous studies of the wizard and the mysterious ways of the sorceror, but in some lands a fierce rivalry exists between the two traditions. Many wizards regard sorcerors as inexpert practitioners of the Art and servants of sinister powers better left alone. Some sorcerors see wizards as arrogant and pompous, deliberately cloaking the Art in mummery and obtuse lore.
Some areas of Faerun are more tolerant than others of the presence of sorcerors. Aglarond, a forest kingdom ruled by the insuperable sorceror-queen known as the Simbul, is perhaps the best example of such a place. Despite differing regional attitudes toward sorcerors, sorcerous talent seems to be spread nearly evenly through the world and the various races, with the exception of dwarves born before the Thunder Blessing.
True to their tendency toward chaos over law, sorcerors worship all types of deities. Mystra, Oghma, Selune, and Shar are popular with sorcerors as deities who have something to do with magic. Lathander, Shaundakul, Sune, Tempus, and Tymora are popular with adventuring sorcerors.
In addition to the familiars available in the Player's Handbook, the following creatures are alos available as familiars in the Forgotten Realms Campaign Setting:
Hairy Spider* (poisonous bite, darkvision)
Lizard (master gains +2 bonus on climb checks)
Octopus (master gains +2 bonus on spot checks)
*This creature is described in Monster Compendium: Monsters of Faerun. A hairy spider familiar gains an Intelligence score, becomes a magical beast (not vermin), and loses its immunity to mind-influencing effects.
The Improved Familiar feat (see the next section of this chapter) allows a selection of more powerful familiars.
Preferred Character Regions: Sorcerors are found in Aglarond, Calimshan, the Dragon Coast, the Great Dale, the High Forest, the Lake of Steam, Mulhorand, the Nelanther Isles, the Shaar, Silverymoon, Tethyr, and the Western Heartlands. Gold dwarves, wild elves, and lightfoot halflings display a knack for the sorceror's arts, too.
