So just a quick question here guys. Was Vivec talking about Apotheosis?
Here is more of the quote so you can get a firm grasp of the context
"However, it is interesting to note that the endeavors of the Psijic Order do not seem to be related to the so-called Psijic Endeavor that is prominent in the providence of Morrowind. When Vivec was asked about the relationship between the Psijic Order and the Psijic Endeavor, he replied:
Nothing but a namesake, I am sorry to say. Now we can end that mystery. The Endeavor is a method of achieving the Tower and then what to do after. The Order is not, and does not really care for the idea of the Endeavor at all, thinking it wrong-headed nearly from the start.
Master Divayth Fyr further corroborates this idea by saying, "...the Dwemer appear to have been most successful in the Endeavor than any mortal. Their Endeavor is not the shared Endeavor of the Old Way.""
