its made to be pretty.

well did you know the butterfly room is where the doctor goes when he's piloting he goes there to have some nature while travelling did you not know that?

i just use the butterfly room as a quiet place to test things. like if i get a new magic mod i'll go in there, summon an army of level 1 bandits and test my new spells on them. its actually much better this way than how i used to do it before the tardis. the qasmoke room is too tiny and random skyrim wilderness is prone to random dragon attacks.

I use it to test out new mods like Vampire Woona said and I place my followers in there.
