There was, but died off, which is what I meant. There was no sentient life when Alterans arrived
To actually answer everybody's questions in one go, because I can always clear up historical decisions and why/why nots of that specific timeframe-
A world was specifically chosen that had whatever requirements necessary for sentient life to arise and at least one segment where it had AND died off.
OOC reasons why that was chosen:
1) All map generation had villages turned off. (No villagers or other NPCs extant were to be on the map.)
2) There was a sorrowlands teeming with undead as a requirement, so it means there needed to be some kind of civilization at some point that later went of the wayside.
3) We didn't want to forcibly insert lore/civilizations on any specific area so we did not /insert/ any cultures onto the NK map so people could be free to assimilate the areas however we wanted.
Note though - ONLY the northern kingdoms and attached south part of the map had that specific criteria, and the rest of the map was going to have other civs to locate and explore and have encounters with. (As per referance, see Council - Culture/Race creation contest circa 3~ years ago.)
As such, there is no actual conflict in the birb-folks existing somewhere else on the map. It's a large unspecified planetoid specifically to allow for expansions as one willed.
