Crystal Valley

The world-altering magic aura surrounding Type-Mercury, AKA ORT.

Crystal Valley is described as having similar effects to a Reality Marble, but working on a different level and through different processes.

This is exemplified in that Crystal Valley isn't a self-contained world or a tight bounded field of immense power, but a free-floating manipulation of the reality around it (akin to making REALITY a Realty Marble).

Its effects are passively transforming the area around ORT into an alien crystalline substance; presumably from Mercury. The crystals are said to be beautiful, but horrendously alien and disturbing. It transforms more than just terrain, as it also transforms trees into horrifying crystal towers. In particular, it somewhat resembles a spider's web, which is fitting since ORT itself resembles a spider.

Supposedly Crystal Valley is activated by ORT's movement.

It should be noted that "Crystal Valley" is a name given to it by Earth magicians and that it is a phenomena that exists beyond names, like all of the Ultimate Ones and their abilities.
