"They *Were* Supposed to stop this... But it seems they have failed in some fashion..." 

Irapx would continue to deliberate on the information he had on hand. 

"Going off what I know... The Heartless have increased dramatically and in power... Overrunning several worlds and have likely sunk them into darkness. I did have eyes on that witch Maleficent but traces of her have vanished and presumed dead so I doubt she had any further involvement in this..." 

That was when he snapped his fingers, something that he had remembered from his youth. 

"There are only a few things that could cause this... And the most likely one is that the Door to Darkness has somehow been opened. From my studies, the only way to close it was using two specific Keyblades: one on this side and the other from the Realm of Darkness. This means either one or both of those special Keyblades went missing or the wielder wasn't present/perished before the door could be closed... Or they were complicit in the door being opened. Any of these scenarios are not good for any of the worlds nor remedying this issue. If left unchecked, then entire worlds will become Heartless masses in due time."

Oban was standing there, part trying to comfort Yumi and the other trying to make heads or tails of what was going on. 

"So... What is going on? I dinnae ken much about all this ye all are havering on about... What is the 'Realm of Darkness' or Keyblades?"

Xanaro waits for Irapx to complete his speech, before speaking up himself.

"I can confirm that this is not the doing of Maleficent. I saw her death first-hand, and had been part of the effort to defeat her."

The blank stare continues, alongside the monotone way of speaking, making the explanation sound rather boring.

"Despite the darkness inhabiting the worlds, it would seem that they still stand- merely corrupted. It is unlikely that they will truly fall. For the time being, at the very least. I do not know how long they have to remain whole."

*Roxie sees the Mansion doors wide open. Did Oban pick the lock? She walks over to her while Xanaro speaks.*

"Realm of Darkness is an empty place where Heartless are born, and Keyblades are magic swords that can kill Heartless!"

*She gently runs her hand through Yumi's hair, hoping it'll help her relax.*
