It seems Ruijerd decided that the place where the Supard race may be hiding on the Central Continent would be in a forest area.
For starters, he decided to move around the dense forest area that spreads out on the southern side of the Dragon King Mountain Range. There, he spent two years searching around scouring the area.
He wasn't able to find any of the Supard race.
However, it seems he discovered articles of the deceased of several individuals believed to have died from the teleport incident.
Afterwards, he would bring those to the nearby town and collect information there.
