Gandharva in sura form attacking planet Gresvan
Gresvan (그레스반) was a planet that was destroyed nearly a thousand years ago.
Humans swore that they would only borrow the Gods' powers for their magic and renounced the sura. Gresvan became one of the planets that was destroyed in retaliation.
Barrier orbs and Visnu's protection of planets happened because of this event as well as other similar destructive events.
In the year D1, Gandharva was sighted near this planet by Varuna. The image of Gandharva in his sura form is a reconstruction based on that encounter.[1] Gandharva eventually destroyed Gresvan.[2]
