Volcania is one of three planets visitable in the Orimus system. It holds an Amulet and a Lost Constellation.
Volcania is a boiling hot planet very close to the sun. It has many cracks and fissures, and a huge ocean of lava. You can only come onto this planet with Corona Wolf wearing the Blaze Amulet, because it is so hot.
