Oh god, there are spiders runnig on walls, Antilons under carpet, Srieker hides under bed, you must be crefull not to step on any scorpions, Schrödinger's cat is in a box and refuses to come out, Immortals and Anubises don't get along with eachother etc.
Sadly there is no room for dragons in my appartment, so use any materials available to build the best dragon lair for my dragons.
