I just killed shadow lich in the abandoned temple next to underground temple of the Unseening Eye?
I found golden skeleton in the tomb, but with no head?
I talked to every NPC in the game, and no one tells nothing about it?
Is it for some higher purpose, or later used in the game???

Look for the thread entitled "Lich quest ??????????" for more details on this quest.
(basically you found 1 of 3 lich tombs, when you get all three the fun begins! the other
two are in the Docks and Bridge Districts)
