You are correct when you compare the sewers to the treetops. Both places

are accessible to only one profession each and both places are totally

safe retreat spots.

You are wrong, however, when it comes to the clouds. While it is true

that only a couple professions can get there unaided, the clouds are

hardly a safe spot. A thief can yank someone from the clouds from any

outdoor location and anyone with high riding skill can get to \"below

the clouds\" from which point traversal to the clouds is possible.

Portaling and gating to the clouds is also done.

Only the rangers and thieves have these \"secure\" retreats. Of course,

rangers and thieves can also cat in a just about any location as well.
