Bestia

The Bestia are a elite extraterrestrial race in the galaxy of Xero, who rely on regularly purging the universe of any and all intelligent life that could potentially pose a threat to the Bestia. After a civil war that lasted hundreds of years, Proelium wasn't purged and managed to grow intimidating enough to rival the Bestia.

Leadership
The chain of command goes as follows:
 * 1) Megiddo the Conqueror

The Pact of Ten Houses
The Pact of Ten Houses is the pact that reunited the species of Bestia. It promised that Megiddo the Conqueror would give his people's powerful bio-engineering technology to all tribes if they joined, allowing The Bestia to rise to their intergalactic glory once more. The pact succeeded, and The Bestia, although weaker, now resemble the once immortal intergalactic empire from so many eon ago.
