The Gem that Caught Fire Sports your typical nonhuman mad scientist type of Chaotic Neutral tinkerer's mayhem. Alchemy, if I do say so myself, is an under-utilized craft throughtout Pathfinder games; and a goblinoid throwing bombs like Link in a china shop reminds me in particular of how a little chaotic comical mayhem can really make a game interesting.
I'm already liking the overall nature of the Umbral Kobold now that I've seen it fleshed out in a story like this. The taunting demeanor mixed with a need to sow a certain amount of chaos makes any character more fun to watch.
I particularly like the imagery I get from the description of the city buildings here; very Tim Burton esque. Shadowsfall is really shaping up to be a nightmare before christmas meets assassin's creed type flavor; and that's always the best kind of city to play in. I whol-heartedly approve and I intend to share Shadowsfall with any group I can get my hands on.
