Branegate

The Immortals created a passage from one universe to another and founded peaceful colonies there, but now the home world is ruled by a corrupt Council that will send an army to put the colonies under harsh rule.

The reincarnated son of an immortal prophet, Trae is guided by a mentor mysteriously connected to his father, is raised to lead a revolution against the Emperor and, reunited with his true family, moves to meet the threat of the conquering horde streaming in from another universe.

Naive story line.

It was hard to grasp the characters. When immortals and brane physics collide I expected more. It was light entertainment.
