Söef

Söef is a fan idea of an enemy type/boss in the Dark Souls video game series. I've created an unofficial headcanon for him that I believe fits both his design and the Souls universe lore (very loosely), but he was originally a crystal chygon adoptable from Scarsji (feral depictions only).

Lore: Söef is one of the many experimental creatures created by Seath the Scaleless while hidden away in the Duke's Archives. By combining a crystal fragment taken from Seath himself along with the fur and teeth of a Great Feline from Darkroot Garden, Seath created this halfbreed drake. As a result, Söef has an innate ability to utilize simple crystal magic, such as crystal breath and homing crystal darts, though he does not have much awareness beyond that of a simple beast. Whether he escaped the dungeons of the archives or was released by Seath is unknown. It can be assumed that Seath holds some type of control over the creature due to sharing his own crystal magic with him.

Characteristics: Söef is a feral, aggressive drake hybrid that lives within the Crystal Caves of the Duke's Archives. When not guarding his territory, he roams the Darkroot Forest and Basin in search of food and sources of magic. He is naturally attracted to other beings that exude magical energy and will attack when he finds the source. Söef can consume crystals and magic users alike to sustain himself or increase his strength. If fed enough, he will go into a crazed frenzy and will attack everything in sight.
