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.

She's like 9 in the present.
Also, it kinda seems that the generals can wear whatever the bleeding hell they want, the high-ranked operatives wear purple, and the low-ranked operatives wear blue. Also, the Edelstein people all wear black.
Therefore, I'm fairly certain that the guy who summons PB and the Black Witch are on the same level, but not generals.
