Kothar hadn't had the chance to rest in over an entire day, to think that he had woken up and gone to a simple meeting with his father, and now he was standing, planes away, in the hideout he had carved out with his Plasma Blade.
As far as he knew, the Eclat's Ascendant was fighting the invading forces' Ascendant, and with their ship destroyed, Kothar had done all he can to help defeat against the invasion. As for what happened now, it would be determined by the result of the battle between the two Ascendants, so Kothar had decided to spend some time on Atla before returning to Eclat.
Returning earlier wouldn't change the outcome of the battle, and if he was better prepared, he would be more capable of dealing with whatever had happened on Eclat when he returned.
