I am going to play the Out of the Abyss scenario with my players, and I allowed them to choose among all available races (fun is my primary objective).
One of the players chose to play an Aarakocra, curiously named KFC. The problem is as following: the Aarakocra can fly (yes, I didn't think this over when allowing all the races, nevermind).
How can I prevent this character from escaping too easily from the prison of Velkynvelve? Are there any spells that can prevent him from flying? Or should his wings simply be tied together?
Note: at some point, he will probably free himself from any binds/manacles/spells, and will probably help with a distraction to allow the others to escape, which I am fine with.
