Obstacle Course.

From Red Dream's farm, he had to return to the tower of destiny before he could move anywhere else. 

This need to always return to the tower of destiny before he could move to other places was a major constraint on his newfound ability to move anywhere. But he soon discovered other constraints. 

The second constraint was that he could only move to places on Earth-11. He couldn't go to the Lignum. 

He also couldn't go to the black market for some reason. The best he could do was appear at the entrances he had taken in the past. 

The third constraint was that he had to be able to envision where he was going vividly before he could move there. But it had the advantage of not needing to have been there before. 

He tested the limit of this constraint by looking at pictures of locations he had never been to before. As long as he familiarized himself with the location and could picture it in his mind, he could move there.
