As Romeo's powers activated some Admin essence in HER blood...she ends up with a brand new form as an alt to her Ender form

Sometimes when she's overly frustrated...she'll go somewhere no one can find her...not her siblings...not her parents...not even Pyroë...because no one thinks to look for her there. That place is the Sunshine Institute. She knows no one would think that. She knows it's dangerous there, but she's protected by her new powers. Especially from The Giant Enderman (That now Roams the outside) and a Giant Witherstorm Hydra (I'll explain that one some other time) so she's not bothered

Bottom line...she goes there when she wants to be alone...and she looks like this. BTW Normally I draw Ender forms with grey skin and dark grey hair and wings. Now to more closely resemble an enderman, they have dark grey skin and black hair.
