Task exploring turned out to be rather succesful - managed to solo all but one
of the monsters and finally managed to get a party to kill the big boss.
Now it can be revealed that the following evil souls were plotting to murder
the Abbess Abigail:

She-Demon of Sodom
a scary ghost (undead)
A small oak tree
Kuzkur, the overgrown hobgoblin commander
A living skeleton (undead)
Billy Bob Jack eyes you nervously
a warrior skeleton with flaming skull hunting for intruders (undead)
a muscular con man is hiding in the shadows
Renegade Knight of Order of Leitbur
A flame green demon
Curley, the Head Thief draws Viper and grins mischieviously
A snow devil spins around here
the banshee spectre of Napoleon von Huber assaults you (undead)
Sister Joanne the goodness herself (a flaming devil grinning evilly)

And eventually:

A voice of an Angel echoes in your mind, 'EXCELLENT work, you have slain the
entire group of evil beings that have plotted against the guild and you manage
to find their spy. Elders are VERY pleased.'

Eye of Zion shatters into million of pieces.

* CONGRATULATIONS! You have completed nun task 'Forces of Evil'*

Small key drops from the heavens, landing at your feet.
