Overlord: An Xylash's Tale

This one I have no idea how it is going to work. It will be about the Overlord, (The Xylash leader you killed) and how he came to power. It will use all the new Xylash units,too!

Here are the scenarios:

Scenario 1
Omega (Then known as Scrak) is a small Grub tasked with finding food for the Xylash Hive. He finds some Zederians and decides to use their bodies as food and breeding chambers.

Scenario 2
Scrak is then tasked with protecting the Infected forms going to the Hive.

Scenario 3
Scrak is then given a new army, and sent to kill an enslave more Zederians.

Scenario 4
Scrak is tasked with attacking the burgeoning Zederian Council, to make the entirety of the Zederians slaves.

Scenario 5
Scrak (Now known a Omega) is given the title of Omega Hivelord. He is then asked to eliminate some Zederian guerrillas.

Scenario 6
An eon has passed, and Omega must survive against the Zederians as they fight for their freedom. The game ends when the Zederians kill Omega, and it appears he is dead, but in the final part, you see he is alive and plotting revenge...
