Universe
The Universe of Tail Gunner was created by the almighty and mythic pistol know as LA PISTOLA UNO. It fired the shot that created the universe, existence, and The All-Gunner. The All-Gunner is an A.I deity (called Gunners) created to build/maintain/and observe the universe. The All-Gunner then created The Anti-Gunner using the revolver of judgement. The Anti-Gunner is a deity of animal level intelligence who can not die, be killed, harmed, or destroyed. She was created to be the universal judge of a culture/planet/society.
One lucky Anti-Gunner managed to have peace for a few million years and evolved to gain sentience. She would go on to become the Demi-Gunner named Luau. Luau was promoted to Gunner of the song of time and given domain. Her powers/popularity began to grow and this made The All-Gunner jealous. As such, they began to restrict her powers slowly, by blasting away her resources, her powers, and limiting the ways she can help the universe.
