The Lanes Between shut behind Larxene and Valixsin, as Aestus was many yards away from them. And by many, it was a few hundred. However, they would hear him quite clearly.
I've been meaning to come to this empty void. Well, I suppose calling it "empty" would be wrong...
Valixsin looked around, her eyes suddenly widening.
Wait...this is!
She turned to Larxene.
We need to leave! Now!
It's much too late, sister. It's here.
Valixsin would look around, before seeing a crimson red tendril work its way down behind Aestus. However, it didn't touch him. She would realize the tendril was miles away, before looking up at the source. A Heartless literally the size of a planet was moving towards them. As it got closer, Aestus would ride off, and Larxene and Valixsin would be able to make out details. It was a monstrous, round Heartless with countless red tendrils surrounding its body. The radiation of darkness off of it was astounding.
Larxene and Valixsin would see that this Heartless world was swarming with individual Heartless on its tendrils, originally having looked like tiny, black, moving dots. An entire legion of Heartless raced towards them.
Larxene...we can't beat this thing. Not just us...
Valixsin looked up in awe, forming her Keyblade.
