Skyrift
Shiren perceives wind as countless fibers and strands, and manipulates them in various ways to control it. He has the power to open a tear in these strands, and move directly through them from one point to another, through way of a pocket dimension. This dimension contains naught but a void of wind, and a single island within the eye of the storm. This is his main power, referred to as Skyrift.
By using Sky rifts, Shiren can travel or transport others across long distances, store items, or even attacks. However, if there is a narrow airspace between two areas, he and others may feel lightheaded upon exit. Areas with no direct flow of air between them (e.g: Underground) are inaccessible via Skyrift.
The appearance of these Sky rifts is either a cyan opening in the sky with a green portal/gateway, or a green opening with a cyan portal. Both are used for entry and exit points. The size of these rifts can range from the width of the entire sky to -literal- pocket size. They may appear in any shape.
Once they’ve been passed through, the tear on both sides are “sewn” shut.
