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.
It might be safe to scout for worlds even if it's not safe to travel to them.
I don't think there's a point without a way of checking whether they have magic or not. I need to read that book the elf translated, see if it lets us guess where to try for a better version of the magic detection form.
Rána makes time to give healing lessons, after double checking that they really do want the magic distributed to whoever wants it; Nidela considers learning it, but ultimately demurs when one of the other stable workers picks it up. Tirinquo is introduced to Maitimo; Rána waits long enough after he's done healing his scars that it's at least plausible she wasn't waiting on that. And as the season turns to winter, she reports that she's found what she was looking for in the book: a tribe of birdfolk are briefly mentioned as having especially complex magic detection spells, which she believes can't have been cast with the normal version of the form.
Cliffs are much easier to target than forests; the tricky part this time is going to be finding enough cover that they aren't spotted.
...and by 'tricky' she apparently means 'not obviously possible'; the area isn't completely treeless, but it's more like badlands than plains, much less a forest.
She gives them a portal to the base of a rock formation a few miles away from where the birdfolk live. It doesn't help; they're spotted immediately by the ones flying overhead, and some of them swoop down for a closer look.
They don't seem have the longest of attention spans; some of them take to the air again almost immediately - but a couple minutes after that, most of the rest of the fliers join the group on the ground. A dozen or so of them at a time ask for words, switching out every few minutes, while the rest - a few hundred - chatter excitedly to each other in a combination of their own language and Quenya.
