Allbreeds

An Oblivion who cannot control their Oblivion Mark is known as an Allbreed. Usually this means that the Oblivion is born with their Mark activated and thus it is present at all times. Leavi is a prime example of an Allbreed and many Elves are also born Allbreeds hereditary-wise, though Elves are usually exempt from lack of control of their Mark and instead only have the all-time-activation effect of an Allbreed.
