SPOILER WARNING!!

So as many of us know, the Five Elders have special powers. One of which is the ability to summon each other via a magic black pentagram circle. Each circle has their own number on it which corresponds to a specific member of the Five Elders. When summoned, they simply rise up from the circle and, as far as we know, they can be summoned from any distance. When the circle forms, black lightning similar to that of Conqueror’s Spirit Haki emanates from them. Topman Warcury, Jaygarcia Saturn, and Marcus Mars are confirmed to have Conqueror’s Spirit Haki; it might be safe to say that Shepherd Ju Peter and Ethanbaron V. Nusjuro has it too. Do you guys think the summoning/teleportation is some kind of extreme advanced Haki, apart of their Devil Fruit powers, or something else?

Fan art I found on Instagram of St. Ethanbaron V. Nusjuro, St. Marcus Mars, St. Shepherd Ju Peter, and St. Topman Warcury rising from their magic circles.

This is St. Jaygarcia Saturn rising from his magic circle.
