The Crystal and the Wizard
A wall conjured by Divine avenues.
When one approaches a Mercury Wall, it will reflect all things except for beings that approach it. If a person tried to pass through a Mercurian Wall, they would keep walking until it seems they have turned around without noticing, for indeed, the Mercury Wall has done just that. Therefore, it has mind-influencing effects. It can be modified to any dimensions, and in the case of Taimyzth and the Kingdom, it created a Bubble shape. To the outside world, it appeared as a reflective sphere of the countryside around it.
