Note Found on Corpse

After months of searching, I finally found the place where those traitors took my little brother to sell him off. For a brief moment, I had hope I might find him, but strange things started to stand out. The awful stench everywhere, the countless corpses, the prison cells echoing with bizarre noises, and test tubes filled with unknown liquids... I don't know what's happening here, but I know I need to get out. Fast.
