The spell Esderand had cast was quite simple. For a period of time, everything within the spell would be frozen, unable to interact with the rest of the world. To any living entities within the area of effect, the return would be similar to a teleportation, except without the change of space.
However, due to the modifications he had made when casting it, the spell had changed slightly. Instead of focusing the return on an empty point of space, he had set it on Vega, allowing him to follow her to the normal world.
Unfortunately, he still arrived at the relative point from where he had cast the spell, which ended up with him unfreezing direcly in front of the basement door, and right next to the sleeping guard, almost waking him up as he quickly backed away.
