The Forbidden Lords TFB

In a world where death is not even the end their are seven lords that were known to be the most powerful of all that they have came across. They have been forbidden within another domain they took as their own, now it is time for them to take back the world that was once theirs.
The world slowly becomes overflowing with corruption and multitudes of desires. The world was in need of change from the lord that was summoned to the realm. It had an academy filled with creatures and beings of prestigious backgrounds.
This alone caused the lord to be interested as he enroll at this academy for a while to learn as much as he can. He try to be the best he can while still trying to control others within his ranks so they don't stray from their original path.
