Zarkon loves this kind of thing, so he'll be all about all of this. (Well, he won't like the despair tar, but I'd be interested in doing something with that.) He will be available both inside and outside. He'll be scavenging, exploring, puzzle solving—and he especially likes fighting things. He doesn't shy away from danger, and if your character needs assistance, he will help. In a rather officious way.

Happy to plot here or on plurk: teacuppity.
