A New Life of the Demon Lord

I am the Great Jherlak, the lord of Fear, the relentless master of the Abyss, betrayed and killed by my own generals... But I still survived! I ended up on Earth, in the body of a powerless human, the heir to a faded noble lineage. Now I have to start all over: find successors, develop the tree of power, and subdue the local clans! Luckily, I have a trump card — it turns out that in this pitiful human world, no one has any idea about the path of the ether! About the abilities that are revealed thanks to universal fear... or admiration.
