Game of Thrones: A Dimensional Strike from Warhammer 40K

[Warhammer 40K + Game of Thrones + no System + power fantasy]

Transmigrated as an Ultramarine, then dropped into the world of Game of Thrones.

The Emperor is missing, his power armor is wrecked, and only one of his two hearts still beats.

Leon considers himself no more than a “slightly stronger” mortal.

He never expected that before the Others came knocking, it would be the melancholy dragon prince Rhaegar who found him, along with a love destined to set the Seven Kingdoms ablaze.

Years later, as they opened the history books recording the earliest god-king dynasty, the maesters couldn't help remarking on how history had an uncanny way of repeating itself: the same unmatched beauty, the same overwhelming strength.

Only this time, the mighty ones were no longer dragons. They were generation after generation of god-kings, whose bodies rivaled the gods themselves!
