Rotten Purity's Cutie Mark ~old~

For those who don't know Runa and Aurich are gods (of time and space) and Lily is a goddess of death (of sorts. she guides souls to the spirit realm awaiting their next body) and Lily is showing Runa and Aurich how to use their new found abilities to manipulate space and time

Rotten Purity however serves a pair of demon spirits and they grant her the ability to manipulate shadows and become part of them as well as other things
