2) Jump on the roof of Borba's Goods and Stores
3) Then jump on the roof of the Newlands Lodge
4) Get on the middle part of the roof you just landed on, and jump to the tower-like roof of
the building in front of you, the Cheydinhal Bridge Inn.
5) Get on the right side of the Cheydinhal Bridge Inn, and jump on top of the chimney.
6) Look Southeast and jump to the roof of the building in front of you.
7) Jump on top of the roof by the tower-like roof, and stand on the top middle part. If you are on it, you will not slide
down, if you do quickly get back on top before you completely slide off.

If done correctly, you should be able to jump out of Cheydinhal.
