Lycan

Lycan, also known as King Lycan, was a powerful Alicorn who lived in Selenos, another plane of existence which the Moon served as a portal to. He is recognized within multiple cultures as the patron of all wolves, who honour him by howling at his moon.

History
After early ponies were granted a spell by Sola which would allow them to control the Sun, Lycan followed shortly afterwards with another spell which granted the Unicorns the ability to control the Moon. After the Hearth's Warming Eve story and the creation of a unified nation of all the pony races, the ponies asked of Lycan and Sola, the Alicorn of the Sun, to lead their nation. Instead of ruling themselves, the two had children who they named Celestia and Luna, and assigned them as the princesses of Equestria.

For a time the world was ruled in perfect balance between Harmony and Chaos, which allowed everyone to live peacefully, but with enough chaos to make their lives exciting. One day, however, the Draconequus decided to rebel against Lycan and Sola, and killed him. Discord, one of the Draconequus, absorbed his power and went on a rampage throughout Equestria.

The remnants of the soul scattered throughout Equestria, and were absorbed by various creatures to create Lycanthropes, otherwise known as Werewolves. Some Lycanthropes believe they can hear the voice of Lycan, who uses them as his pawns to act to protect his daughters, and the balance of Order and Chaos, or enact revenge upon the Draconequus.
