A small parchment is pinned under the poster by a short blonde haired Lantanna woman with a bespock pair of brass and leather goggles resting a top her head.
Miss Vana Weaver,
Dlarun is an excellent bone-white metal - often mistaken for ivory - that has a distinctive greenish sheen in candlelight or when in the presence of magical energies. Dlarun is suitable for carving and sculpting during the crafting process, acting more like a soaplike material until hardened in the last stage of the material's forging process. Dlarun is a product of the hins, so I suggest looking in Shallybrook for a suitable smith.
If this is still not a suitable material, then I'd suggest a favorite of my own. Copper! A very soft, malleable, and pure-metal material. Copper can be thinned into sheets for rolling and bending as if parchment, and a simple steel burin will do the job of writing into the material. An easy task that can be performed by any apprentice or even novice level smith.
If, however, you only need to be able to write on to a metal rather than carving into the material, then a simple paint applied by a fine brush will do. The simplest methods are often the best methods for a reason.
