Figarland Garling is descended from the original rulers from Elbaf and his yokai transformation would be Fenrir. Basically Shanks is the original prince of elbaf, that’s why he chose the island as a major base. Fenrir is a giant wolf from norse mythology that is said to set the world aflame and start ragnarok. Garling would start burning the world down which would lead to end war. Fenrir is also the name of a moon of saturn. Also, its likely that Garling would show up at Elbaf as a major villain, killing the ruler. In the end however, shanks would defeat Garling.
