Hello there, dear Magnum Opus Author,
I recently began to search for Overlord Stories on Wattpad and stumbled upon what seems to be a stolen version of your own book under the same format except for the Title. I strongly suspect that the thief came across your Story and copy pasted it with a side-note at the first chapter to make it look like they had the idea themselves.
You can find it under the name of “Yelloness” by Perody. Hope you can shut it down if it’s not you.
