Gibbet-nice "castle" over there. Small library (i needed to deliver there two books, i got from Forsaken Outpost), Living Quarter and Small Storage room (with deathtraps for good measure), Chapel (too bad it got destroyed, after putting a Yorick's Skull on statue), Dungeons (this will be covered in next episode) and Sewers.
Effluvium- it looks like Stalkers live generally in aquatic areas, but they prefere murky waters, and castle sewers are not an exception. I had to go there for Dungeon Key, needed for unlocking other level. I got a feeling i will visit Effluvium more than once.
