Who: Jace Beleren and Armand St. Just (and OPEN if anyone else wants to multithread me)
Where: Level 5, wandering around
When: Not too long after Jace has arrived.
Warnings: Jace will read Armand's mind a little bit.
The ship was large enough that learning its layout quickly would be prudent, particularly considering that it was being used to hold and rehabilitate dangerous inmates. Jace was still trying to figure out exactly what the ship was and how it was able to operate the way it did. The only thing he had ever been in or heard of that came close was Tezzeret's stronghold.
Jace made his way down a hall, tired and still not fully recovered from his recent ordeals. He would need to rest, and while a nice little island vacation would have been preferable, Jace wasn't going to complain about his current location. An opportunity like this did not come along often, and given that this ship seemed to be in constant motion, the chance that any Planeswalker would encounter it even if they tried was slim.
It lacked the defining characteristics of a Plane, and it seemed to not have proper mana production, though Jace could feel some coming from above him somehow, rather than off to the side or below him.
