Orim of the Shadow:
All the previous owners of the jewels became undead? The Black magic dwelling in the jewels must drain the life energy of the owner...
Normally, one would throw away or destroy such jewels, but these people held on to them too long... I suspect that the jewels held some other power over those who possessed them...
This power must have something to do with the box. Well, we won't know until we open it. All that remains is to insert the jewels, each in its own space, in the correct order. Now, give me the jewels!
Give the Gems of Aklantoth to Orim.
