Seems like they're preparing a new part of Time Temple.

I'm going to assume her having Ereve float is why she can't do anything. They say she is "young and fragile" but clearly, she has a lot of powers that could be a great ally in any battle. (Which once again leads up to her acting completely fake. Cygnus, ihu, y u so mean to mapleworld? STAND UP AND FIGHT! ;-; )

BTW, I manage to look through my stuff and found the extract sprite for the guy who summons PB:

He looks like Akyrum's santa-fied self or something. I dunno, I just thought it would be a nice fun thing to look at, seeing how it took me forever and a half to find his sprite and we're talkin about him.
