First mention on Day 200
Warpidron is first boss Rou encounter on the fifth floor during his conquest of the [Age of Gods] dungeon [Aquarium Forlia]. With a horn shaped like a wave on the surface of it there was a huge whale's head, and then there was a huge body with eight legs. Long, like a snake's tail hit the water. Four huge red eyes, tirelessly watching its surroundings.The entire body is covered in a massive ultramarine colored skin with a metallic sheen. A huge monster, 15 meters in length, a height of 7 meters, and a width of 5 meters.
