Burn down part of the stockade, escape throught hole.

Can I still use magic? If yes, use telekinsesis to loosen stones from the wall to use as footholds to climb for the window. Get about ten feet up and wait. When the guards come in wondering where I am, drop down and knock him out. If no magic, tie my bedsheet into a noose and act like I’m going to hang myself, then strangle the guard with it when he bursts in.

Teleport out.

Who is the PC? It would be annoying to find out one was a pegasus after building improvised climbing equipment out of your own mane.

Fap at the speed of light and blow out the walls.

Fuck bitches  
Get riches

How far apart are the walls?

use chakra and walk up the wall, open the window and check for guards. then scratch a mocking mesage on the wall about ninjas before leaving.

Get me something flammable  
Get me something metallic  
Make a cylinder with the metal  
Put flammable material inside  
Ignite  
Ride the rocket out

Fly up, being a pegasus and all.

Yell at Window
