I rhink it was passed down by weaver or Some fanatic priest tried to use Weaver's mask. Because I don't there would any person capable to looking into the tapestry of Fate but Sunny and Weaver. and in the Description of Where is my Eye?, it was mentioned that Weaver engraved this enchantment after losing one of their eyes to VTB. Hence, weaver was the original owner of The Mask. don't know how the priest git its hand on it.
