In Biscord, Felix usually jumps from server to server. But there is a particular set where he always returns to.
One of which is the Lemon Club. Contrary to the name, they don’t have anything to do with lemons besides the occasional talk about lemonades. The server’s pretty chill and Felix has been a core member of it for the past six months. He knows the members by names and faces, even their story during his whole stay there. If he’s going to try and use his powers, it’s perfect for first tries there.
There’s BSC - Body Swapping Club. It’s a server with body-swapping and possession kinks like what Felix does. They would lose their collective shit if they knew Felix gained the power to possess people.
There are other servers and he could search for more online.
