There are two possible solutions, that I can think of;

Reviving dead NPCs - can change character locations (via hex edit), though this does not necessarily work on characters that relocate due to plot development, as Eolus does.

FIX for the Missing Catacombs Portal / Josephine herself stuck in the wall
requires a file swap and restore from a save at a corresponding point, which may or may not cause a problem during the blessing ritual (when your original file was swapped back, the game would think he was in the village, rather than the council hall)
