In Second Coming, the alien/mutant Ariel was killed by a missle strike on the car she was traveling in with Wolverine and X-23.

However, Ariel is a teleporter capable of linking two doorways.

So my question is this: What exactly are the limits on her teleporting? Can she link any two doors or do they have to be the standard rectangular-shaped door. I never read Fallen Angels, and was only introduced to Ariel when she made an appearance during the Utopia event, so I have no idea how her powers work.
