After making the dwarf "Cooperative", we now had a problem.
As mentioned before, I fallowed the necromancer through his tracks as well as found out the poorly made fake wall that hid his passage.
Even if I didn't found it, it would be still matter of time before the guards would have found it.
And going back to the city and covering up the exists is out of the question, since the guards maybe already checking out the sewers. I straight up doubt that place is filled with brainless idiots and wouldn't check the sewers.
The exit of the tunnel is nowhere near our current hiding spot, but the city will be aware that the dwarf had left the city and was in this forest.
They may start making search parties in the forest and if players start getting here, oh boy. This will get annoying.
However, the necromancer had already a plan to move out into his laboratory. He was more prepared than I though.
Well, that was bit obvious.
