David finds the location of the old domain in an old document, the document shows that the domain is located near a city with plenty of elves. The reason for this is because Plantae's God is fond of all living creatures, Mantis holds a close relationship with the elves' race hence because of his nature-loving and nurturing personality.
It is said that the domain is well-hidden by the elves, they support and pray to Plantae's God for their homeland prosperity. Mantis is loved by His supporter and peers, but perhaps those prayers disappear when the Gods decide to hunt Min Soo's life to ensure the peace of Sanctus Luminera.
As a peacemaker God, Mantis decides to stay away from any conflicts that bother his duty as a Plantae's God. However, his submissive nature causes him to keep a low profile as a God.
