Just needed to clarify some things:
Diablo is like a slave owner, and the feral Kani is like a puppet
Kani and Diablo have merged into one ultimate Demon as he keeps reminding me in the past.
They fight each other, because each of them are individual beings.
Do you know the Humans that the Terrans descended from? Those of Old Earth? There were some kings that could control those they ruled to not fight among each other without any sort of Overmind. That's the same way down at Kaldious.
Now on to the story:
*Small Mentalope creeps among the Demon Hatcheries, its body hidden by a camouflage suit*
*It reaches the larvae and imposes its mind upon them*
Mentalope: I am the Overmind. Your true master. You have been birthed with the wrong leader in mind. Your freedom from an overriding will corrupts you. The Overmind is supreme. Come back to Char with me. I will free you from corruption and leave you the rulers of this Universe.
Larva: Our daddy is here! Long live the Overmind!
Mentalope: Yes, I will take over this Hive and your brothers and sisters will join you in the journey back to Char. Now, morph into more brethren. You will need to break free of the Terror Zerg before you can leave.
Larvae: Yes *morphs into eggs*
*The Mentalope moves around the Hive, making everyone think he is the Overmind and getting them ready to break away from Kaldious.*
Queen: But, I cannot see you? Where are you Overmind?
Mentalope: I am on Char, but my mind is here by you, driving you in the right direction to the Zerg Swarm.
All zerg warriors: Long live the Overmind! We return to Char!
*The Mentalope slowly exerts domination over the misdirected zerg. The zerg will soon become mindlessly obedient to Khalazar and no one else.*
