Obsidian was a material. Fortress Vader on Mustafar was a tower built out of obsidian
Blue Sheen Obsidian is caused by the fusion of Blue Diamond, Pearl, Amethyst, Ruby, and Sapphire.
It could be found on Bassadro, Mindor, Mustafar and Nam Chorios. Sometimes, a fry-rock was composed of obsidian, and the material was used in part of Darth Vader's armor, the Shadow Throne, and also to make obsidian lances and obsidian swords. Kinnin Vo-Shay also had an obsidian talisman, which apparently had lucky properties.
Obsidian is a smooth, dark rock that is made out of hardened lava.
It is also the sharpest substance in the known universe in contemporary science.
