Obsidian

is a material that comes from the shards that fell from the sky when the moons collided during the Cataclysm. This material has magical properties that the Cabal of Obsidians used to power their magic.


 * The power of the Obsidian Cabal sprang from the shardstone that fell from the sky, and nowhere was it more concentrated and potent than here in Desolis.

Some creatures exist that are made out of pure such as the Obsidian Golem. These creatures are immune to magic attacks.

The magic school of Chaos exclusively utilizes small fragments of this material, known as Obsidian Chip for a reagent for this school.

Trivia

 * Obsidian seems to be fragments of the shattered moons caused by the Cataclysm, and not related to obsidian glass. It shares many properties with Blackrock in the Ultima series.
 * Obsidian may be named after the Obsidian Order, or vice versa.
