Well, this was unexpected. Get tactical Marines!
Five armies battled each other,
A newborn Alliance, a fading one, and a Legion;
They fought for the destiny of the galaxy,
And all its life.
The Newborn tried to stop them, but they were weak,
And gods must be strong.
Suddenly, ancient enemies turned into friends,
But when the Voice was silenced,
They started their fight again.
This is kinda easy.
