Artroy Branches

Named after the conjurer who first developed a way to move along them, Artroy Branches are the common name given to a phenomenon experienced by any sentient being attempting to use long-range teleportation magics. According to those who have survived such attempts, the complex spatial paths that must be navigated appear similar to an infinitely large map of crystalline branches. Due to the inherent difficulty of moving between branches with any degree of accuracy, successful teleportation requires extensive knowledge of the spell used and these Artroy Branches.
