Dear Terry,
I've been wondering about the Xiosians since Atlas Addenum / Emer -book.
They were supposed to be source of Changramai techniques - however they wielded Dags and were warrior priests. Later on that approach has changed (Emer I and esp. Emer II)... They do preceed Changramai however.
I've always thought them above average master Changramai but below Herald of Night power level
According to Emer book they are still residing on the summit of Votania.
Dear Tommi,
Most of what we know of the Xiosians remains apocryphal, although master Changramai have confirmed that their original martial arts teachings came from Xiosian warriors who defected from the guard of the Masters. They also maintain that the Masters survive to this day in a vast temple complex atop Votania, the entrances guarded by immortal Xiosian sentries, all in a sort of sleep-like trance. No one in this age has been able to reach the summit of Votania to verify any claims about this legendary acropolis.
While called 'warrior-mages' by some, most Xiosians were advanced martial artists (trained in unarmed as well as armed combat) with some spell abilities. Some were apparently more powerful than others; these were an elite personal guard for the Masters. As far as we know, all Xiosians were Elves, most likely Loari.
I hope this answers your reference request.
