Still, Where Would An Artrium Be In a house?

Wow man. That's very odd. (laughs) Heh. Space and time, eh? Maybe your house has one. Maybe a Soul Eater is going to devour your soul tonight. Soul will have dinner. Yum.

it's a portal between time and space where i hide to be inside of your house.

Just curious- What on God's Green Earth is an atrium?
