Mysterious Painting 1: Origin of the Lopters

Years ago, the lunatic artist was mocked by the people because of his lopters painting. Time went by and the artist found his old painting being transported on a suspicious cargo ship, which became a catalyst for revealing the origin of the lopters. Thus the days of speculations have passed, and an era of active in-depth study of the lopters have begun. The lopters are thought to have been created by Vell and Khan because of their longing for each other, but it is yet unknown what kind of messages went back and forth.
