The Warlord's Revenge

Imelda says, sighing, "Though we don't have land, we do have domains. In front of you is the deepest water; it can swallow seven earth's (Earth gets used as an example, as almost every being knows about Earth). As for what I mean by up, yes, we don't have solid land, but we do have air and a sky." 


As Imelda strikes a ray of light up in the north direction, the boys are amazed to see two huge water bodies above their heads. They could actually see the bottom, and likewise, on the east side, they saw three water bodies. 


Since they could see the bottom, they could see the serpents as well, with the banshees swimming on the surface. 


On seeing this, Vonruil says, "According to me, the north has about a hundred, fifty in both, and the east ones have hundred-fifty to seventy. As for this one, it should also have the same, but the depth is definitely a depth we never ventured."
