Amber Temple Nothics, how would they act?

 CoS book says they don't attack unless attacked. Use their weird insight ability.

Noticed that they have Truesight, so they'd know the Arcanaloth even if it were trying to be disguised. Their INT is 13, but they are insane, so would they give away the Arcanaloth? They mostly covet magical things and knowledge... but they are the old wizards from way back when (original wizards or visitors since?), so if original, how much knowledge is missing vs. they have learned? I guess always room to learn.
