Necrosyrtes

The Necrosyrtes were a race which Fairy Aeryka claims to have invented dragon metal, as opposed to the Mahjarrat or Dragonkin. No other mention is made of Necrosyrtes, so very little is known about them.

'Necrosyrte' is a genus of vulture, so these beings are probably the Dragonkin, since they're physically similar to vultures. In the nineteenth Postbag, one of the letters, answered by a Green Dragon, also says that "The very weapons that make you strong bring Kin's return ever closer", another hint that the Dragonkin made dragon metal, as they also invented Dragons.

According to Movario's notes, "The demon birds, evil bird spirits of the east: dragonkin, or something else? I have so far deciphered that these strange phenomena are mentioned only cryptically, written down by adventurers who have become their hapless victims. The dragonkin's arrival seems to pre-date most things. In short, the arrival of these creatures - whatever they are - seems to signal the absolute destruction of any local area they are visiting. I suspect that they are creatures brought here by gods to support them during the god wars. Also, I suspect that they are responsible for the metallic 'dragon' items. Where this material comes from is still a mystery."
