I am a Duergar A-P

First time I see him at level 5:

civilized <100%hp 100%m 98%mv 1856tnl (41.08%) 10 PM> e
The Work Floor


The dwarven foreman of the lumberyard patrols the work floor.
A lumberyard worker tirelessly strips the bark and limbs off a tree.

He says nothing...

quests:

Shows nothing about 'Rat and Spider Extermination'.

At level 8 I go to him again:

The Work Floor


The dwarven foreman of the lumberyard patrols the work floor.
A messenger is delivering the latest news from the forest.
A dockworker strains under the load of a large river-soaked tree.
A lumberyard worker tirelessly strips the bark and limbs off a tree.

again he says nothing... then I kill him:

The lumberyard foreman is DEAD!!
You receive 130 experience points (35% bonus).

No says or echoes of any kind... and I am still only level 8...

quests:

Completed Quests:
Failed , Lumberyard: Rat and Spider Extermination

Which is it: I couldn't take it, but I could fail it, or I could take it, but no echoes?
