The Mantis Monarch was shameless, but this rare trait was what saved his life from the claws of the indomitable Lord of the Shadow Realm.
Lord Elrond of the Wood Elf variant human race was already a powerful opponent to go up against for this Mantis, adding Sebastian into the equation was overkill and he knew his limits when he saw it.
The Mantis Monarch didn't even deem it right to at least put up a fight, once the 2 enemies appeared, he surrendered in the most shameless way possible.
Sebastian was left speechless and surprised after the Mantis Monarch was done, but by then, all his animosity towards it already evaporated like the wind.
Sebastian only needed to think a bit before he arrived at his decision.
Unlike Lord Elrond, the Mantis Monarch was indeed shameless for calling himself a Monarch. Unlike the Wood Elves, Mantis was uncommon in Oceania, they were a rare specie of beasts in Oceania with some of the lowest populations.
