Magic portal

Magic portal is an animated piece of scenery on the top floor of Watchtower. It can be assumed that this portal is tied to the Watchtower teleport spell. It otherwise cannot be entered or interacted with.

Appearance
The animation is comprised of several small blue gray clusters rotating left to right on each of the four sides of a square, so that each side is going in an opposite direction. It is almost identical to the Portal animation.
