They've left him alone in his cell.
He can't really be said to be lucid but he has very acute instincts for when there's someone and when he's alone - it's the last of his senses to depart him - and he's alone.
And then suddenly he isn't.
Pretty far? Not, like, months away, usually, but a group that decides to go exploring will usually be gone for weeks. There's a big riverbed that gets water in the wet season out to the east, and desert to the east and south, and if you go far enough north there's forest but you have to go really far, and the mountains where the goblins live are to the west, and west but not that far west and a little north is the ravenfolks' village.
Sure!
The library is tucked away behind the art gallery, and it's not very big at all, just a couple hundred books. Most of them are descriptions of the surrounding environment, or accounts of historical events, or instructions for crafting or aerobatics or gardening or other things. One wall is devoted to storing scrolls, mostly various sorts of records - of agreements with the ravenfolk, of agreements between flock members, of various events that they might want record of but that aren't interesting enough to have an entire book written about them, and so on. There's also a section of the scroll wall devoted to maps; their map goes there, though the birdfolk seem to think that someone will make a frame for it sooner or later.
It's the way it is so they can write in it! They don't have as much rage of motion in their wrists because of how that joint has to also support the last section of their wings, so they have trouble making some of the loopy shapes that other alphabets use.
Here's the sounds the letters make! All the really simple books are up by the hatchery but someone could fetch a few down if they want something to practice with?
