You fill a sack with everything important you can get your hands on. You slowly and carefully make your way back out of the abandoned tunnels. You rent a small room and store everything there. Then, you go searching for revolutionaries.
It takes a while. They're quite good at hiding themselves. Eventually, after enough suspicious conversations, you're approached by a handsome rat.
"So, I hear you're looking for us."
You explain what you have found.
"That's incredible. We could use your help. This intel could change the course of the revolution."
You give the rat the key to the room and directions of how to get there. He takes your paws in his.
"You are a true friend of the revolution. There's a bar in the Lower City just south of the Chinchilla War Memorial called the Squeakeasy. Cheesy name, I know. That's where our hideout is. Tell them Ed Hamster sent you."
He walks off following your directions to retrieve the intel.
