An exhaustive list is tricky. And these aren't recommendations, so much as refreshing your memories.
The original "out of town" plot hooks
There is the "town in the distance" which somebody saw from a high point in town. (we can say that Silvi saw it from the top of the growers dome when she was retrieving a wounded bird for her sister). - this was NNW of town about 65 km (40 miles)
There is the "ghost district" of the town -
this would bring you very close back to town
The bridge across the river -
this would also bring you very close back to town
Other hooks
Silvi's messages -- the bird comes from somewhere
The snake -- was coming from the swamp south of town
There is the actual geography of the town, the river runs north into the hills, and south into the swamp. The forest (which you are in) is thick to the west. The east wasn't really discussed but I'm thinking its a sort of plains.
There are also some things that you'd probably have trouble following up on (in the sense that they don't say "go east" or "go west")
[sblock=Old Hook's Paintings]
- a small village
- a great city full of Gothic imposing architecture, horned figures feature prominently
- a "white world", the ground is white like it's covered in snow and the walls sparkle
- there is at least painting that Old Hook drew and destroyed, Karothen found a few shreds lying in the gutter (they had apparently fallen from the roof) -- Old Hook painted nothing after this painting for a long time, to the point that Karothen had begun to fear he would stop making paintings at all
- hew added a few more but I can't find them now

Early "places to go" draft[/sblock]
There is also simply striking off in a random direction and "exploring the forest", if either of those suits your fancy.
