If the character had History Nomikos or Loremasters or Althans... would Andraxx come up??? Nomikos, No. Loremasters, No. Althans, Yes. But the last would be a difficult research project. You would also have to do a great deal of research to even realize what an Althan is.
I think you have that a little backwards. Terry has explicitly noted that only a handful of people actually know his true race. I wouldn't rank some basic knowledge of Andraax as too obscure but what little is "known" would be myth and ancient history. On the other hand, I would think that history of Nomikos, Loremasters, or Althans would all be highly unusual skills. Althans would be known as the mythical Lords of Essence and you would find absolutely no reference to Andraax there. You might find a reference to Daenku but connecting him to Andraax would be virtually impossible unless you meet him in person and ask nicely.
Basic information about Andraax, the Elven Sage from the early Second Era, would be much easier to find. There's a giant statue at Nomikos so you could easily learn about his role as the founder from anyone who had actually been to the Library. The Scribes would also probably tell you he was one of the three founders of the Loremaster order. On the other hand, I doubt that very many people even bother to ask about the statue. And of course the Scribes would also freely tell you about the "fact" that he was buried long ago. I'm sure that if you asked about the six fingers on the statue you'd get some comment about "imaginative artists" or some other way to dismiss the quirk.
The Loremasters might mention his name as one of the three Founders, but of course, their history shows quite clearly that the Order was founded by "three Elven Sages". And the one remaining Founder, Kirin, still heads the Council. For centuries even the Loremaster's didn't know if Andraax was still alive.
Andraax is a figure of myth and legend from the early period of the Second Era. Very few people would even stop to consider that he might have been active in the middle of the Second Era much less still live in the Third.
If you delve more deeply you might find an account of him showing up at the Wars of Dominion, but in that case people would probably assume that he died in that conflict. After all he hasn't done anything "public" in the entire Third Era.
