tenebria

One of the Antagonists of the DLC The Ark of Time to the Playstation game Gravity Daze 2.

Tenebria is the physical form of the Element of Darkness.

Much like Lumino, whose name is presumably derived from the Latin lumen (light), Tenebria's name can be surmised to be based on the Latin tenebrae (darkness, shadow, gloom, obscurity).
