A portal of darkness opened up on the world, rising from the ground in the form of a doorway. The white haired heartless walked through and looked around not having seen this world before. 

"This appears to be a kingdom of sorts..."

Waving her hand, the Dark Corridor behind her would close and vanish as she began to wander aimlessly. She felt something drawing her here and wanted to make sure the source was eliminated by her own hand fearing it might be another Dark Heart drawing Heartless to this peaceful world.

*Silax saw as Suke entered the world, hiding to not give away her presence just yet. However she would pull out a card and throw it into the air above suke, it glowing before becoming black. A few heartless would then drop down from the black card, falling around suke. The group of shadows surrounded Suke.*
Marie
Suke would still walk, oblivious to Silax at first. She stopped when the card landed at her feet and turned black. Her eyes narrowed when Shadows appeared and began to surround her. With a twitch of her hands she would summon her twin guns and was ready to fire but glared at the direction the card came from keeping her neutral expression and monotone voice. 

"Who called these Shadows here?"
Kathryn
*Silax's voice would seem to come from multiple directions* "It would be better to ask why you are here, the heartless that allies with light..."
Marie
"I want to see what is going on in this world..." 

Suke replied, hearing the voice come from seemingly multiple places. She still found it extremely weird that she couldn't sense a Dark Heart nearby despite someone clearly Summoning Heartless in front of her. 

"But why are you concerned with what I am doing?"
Kathryn
"It's quite simple... You are a heartless, and yet you choose to fight with those who want your existence eradicated. It defies logic... Unless, you are simply using that boy to get close before devouring his heart." *Silax laughed, the heartless responding and attacking Suke, though they were very weak and shouldn't be a problem to Suke.*
Marie
Suke wasted no time, firing her guns and planting a magic bullet in each one and slapping the final one with the barrel before dispatching it with another shot. 

"That is not true. I have no desire to devour hearts only to eradicate those that seek to do so." 

With them gone, she still looked around for the source of said voice having her guns ready in case this person tried something.
Kathryn
"See, it makes no sense. How could a heartless want to eliminate their own kind in such a way? With how powerful you are, you should be leading hordes of heartless into worlds, gorging on every heart you can get." *Silax would jump out of her hiding place and land behind Suke.* "I wonder if you are just following Ika's orders by instinct..."
