Rahovart Altar

By default only usable in the Nether. An altar made of 5 Obsidian pillars, the 4 outside pillars are 4 blocks tall topped with Diamond Blocks and the center one 5 blocks tall with a Demonic Soulcube at it's core. Upon activation with a Soulkey, the Rahovart Boss Event will be activated. It is similar to the Asmodeus Altar only the surrounding pillars are corners from the center rather than sideways.
