Riftwalker:
A 5e Sorcerer Subclass

A part of your being is bound to the fabric that connects material space within and between planes. Through this bond, you have found yourself able to create and manipulate small tears or rifts between physical points in space. Your innate magic flows easily through these rifts, eager to burst forth, a task some are better able to keep under control than others.

“Riftwalkers,” the term by which these beings are often referred to, are seen as oddities or curiosities in the arcane realm due to their seemingly unique and inherent position between the arcane and material world. The origin of their bond to material space is a mystery.
