Dearie,
I know things are hard, but I won't abandon my post just because you're feeling a little worn out. My duty to the knyaz is far more critical than some leaking roof or wilting crops.
You'll manage. We all make sacrifices...
Unfinished Letter
A loyal soldier's letter to his not-so-significant other.
The quest thread it belongs to
The game files this document under one quest code, and that code covers all 2 of these journal entries. It belongs to the thread; the data does not say which entry.
Where to get it
From the game's own loot tables and the inventories its characters carry. A percentage is the highest spawn chance recorded for this item; a row without one always carries it.
