Yes, there was a previous Shadow Monarch who was defeated in battle. There are many monarchs like The Beast Monarch etc. but the 2 strongest are the shadow monarch, who rules over death, and the dragon monarch, who rules over destruction. Due to specific events that I will not spoil for you, the 2 of those most power monarchs fought and the Shadow Monarch lost, and died. His powers and later on, his memories are slowly being transferred right now to our protagonist.
Hmm, nah, I'd say that the events of that statue room were meant as a sort of test, and his strong will to survive is what had him pass and become qualified to eventually become a monarch
Hahaha Beru... practically stuck his tongue out at that creepy undead. I have to admit, Beru creeped me out before he became apart of the Shadows.. Now, he's my 2nd favorite to Igris.
are you fucking kidding me bro they where talking about him they want to be apart of the monarchs army damn this manga never misses a beat every chapter is so good man i feel so satisfied after a chapter but some other mangas do shit in these areas they drag the arc to long lixfan for example
