Rune is the last known surviving member of their people, known as the anve. The anve had a form of innate magic from birth/spawning in that could be awakened to its full potential by the tattooing of a "Blessing" on their left shoulder blade. Rune's fellow anve died before he reached the age at which the granting of the Blessing was considered safe, and as such he only possesses the weakened forms of anveic magic; most notably a small radius of comfortable warmth that fluctuates slightly with his mood, and some degree of innate fire resistance. He has some control over his wings, but not enough to fly properly. Rune lives in a taiga biome that has been somewhat reforested, with two cats named Wunjo (tabby skin) and Gebo (persian skin).

The anve "resonate" with different types of magic in different ways, which informed how comfortable they were around these magics. Nether magic has a strong positive resonance with anveic magic, granting anve who are in or near the Nether a sense of comfort and reassurance, and in some cases faster healing. Void and Aetheric magic (correlating to the End and Overworld dimensions, respectively), however, have extremely negative resonances with anveic magic, causing physical illness, pain, or even death if an anve interacts with a source of one of these two types of magic for too long.

This negative resonance is why the anveic population declined so sharply each time the End Portal was opened - the sudden influx of Void energies led to widespread illness and death among even the strongest of the Blessed anve.
