Senchous camp

You arrived at a camp consisting of five small houses and some outbuildings located outside the camp grounds. The camp itself was surrounded by an old wooden fence, easily climbed, and beyond it lay a clearing and a couple of sparse trees.
Today, you arrived at your destination by bus. A cheerful melody was playing somewhere, and birdsong could be heard. You got off the buses (there were only three of them) and were directed to a large clearing to begin assigning everyone to teams.
The assembly was quite noisy. Some strange guy decided to set fire to some dry grass, and his dark-haired friend, about the same height, stood nearby, keeping watch. As you've heard, his name was "Friend," and the guy who set the fire was Senchous.
This camp's counselors are: Alexander/Uncle Sanya, Doctor Strange (yeah, right), Fraze, and Grandpa from "Grandpa's Pizza" (and why not?) (you can choose others). There are also other characters, and you can choose who they will be as the story unfolds.
