[By all means the ledges should be climbable! And yet...]

Now that's a question, isn't it? I honestly have no idea, I know there isn't exactly the usual bureaucratic process when forming a business here, most of everything is rather unregulated by my measure, unless it specifically involves a native. You will of course need to own the property and all that, but otherwise... Perhaps it would simply slide under the radar unless someone reported you to the authorities, but I cannot imagine anyone would care enough to do that.

Unless you have enemies, of course. You don't have any of those, do you?
