I've often wondered if I gain necrojuice if something died that I injured when I wasn't in the room. I think this answers that question:

[Old Ta'Faendryl, East Market]
You notice a curved silvery blade and a twisted crystal-tipped staff.
Obvious paths: north, east, west

As you savor the end of the Ithzir scout, you feel you have satiated your desire for necromantic energy for the time being.

A war griffin soars in.
