I was given the awesome opportunity to work on the Apostle's Library space for Diablo 4 Vessel of Hatred. My responsibilities were initially to worldbuild a brand new space that sold the narrative of a hidden library, lost to time, that players could find at the end of the quest dungeon. It was later decided that this worldbuilding could be set dressed to some of the rest of the Teganze Cave tileset as well.
The Teganze Cave tileset owner was Sungjae Cho, who's excellent worldbuilding provided the base for the set dressing which was propagated throughout the cave prior to reaching the library space itself.
