Blocked entrance in Marshan swamps

[Tempo]

This crypt is non-worked in KB:TL. Developers has an earlier idea to create quest with it, but they has been refused that idea in game creation process. So this crypt was leaved as landscape element only, and its entrance was blocked.
There is corresponding info somewhere in russian forum.

All this makes me think of that zombie, the first time talking to him you can ask to see what he has for sale, he declines. Afterwards he only says Go away or something? Is he for a much much much later quest? Considering I was around lvl 5 when I first met the zombie.. and im lvl 22 now >.>

He's part of a quest from the alchemist dwarf in the swamps. The only way you can get the quest is to first get the quest from the witch to sabotage his experiment. Let the dwarf know that you were responsible for exploding his experiment before you 'turn in' the quest with the witch. If you talk to the witch first, he'll never give you the quest for the zombie.
