We all know that the absolutian warrior named tartarus is one of the most powerful villain yet, and he posses the power of space travel and also time travel.
So when his first appearance was in land of light, his first thought was the planet is beautiful (suitable for absolutians) and his goal in the series is to conquer the planet by kidnapping princess yullian (which he failed)
And tartaru's planet home (the kingdom) is dying because of the enormous amount of power releasing from their differatoy rays, forcing him to find suitable home for absolutians.
But with the power of his space/time travel, he can go back to past and future, so why can't he go to the kingdom in the past? Instead of conquering while he can travel from past?
