Haiku Hitman
Danger level: Hostile to Templars and goody goodies. Don't show up rich. You can get conned or your stuff stolen here. Apart from that, if you mind your own business you're good.The level of danger, the rules of the place, the power structure of the place, rumors about any powerful objects currently residing there, any insider knowledge he would've come across as far as the perfect way to butter a specific seller up to get a decent discount, and of course, where would be able to safely bathe. Priority in that order.
Rules: Don't ask too many questions. Respect the Beatdown Gang
Power structure: Run by the Beatdown Gang headed by Sully Stabber
Powerful objects: They collect the deadly rain that makes you age quicker from the Arid Badlands here. They also have wood from the remains of the stump of the manna tree that is resistant to this rain. They use this rain to quickly grow food (booze mostly) which has helped them survive in the desert. Powerful artifacts aren't kept there, just passed on quickly to potential buyers. This is the place where exchanges are made, while the artifacts are kept in the hideouts of the bandits before any deals are made. Last rumor is that they are designing a better solar surfer engine than before from machines excavated from the ruins in the badlands which is drawing some potential riders who love the sport of solar surfer racing.
Buttering up: Sully Stabber likes fast things. If you have anything to offer to solar surfer racing engineering, you'll get along just fine.
Bathe: Yes, there is one bath house there next to the walled up oasis that the Beatdown Gang controls.
