Back to Gaban’s house. Shanks explained Gaban how “contracts” work while he showed Gaban the mark on his left arm.
Shanks: “Me and Harald formed a “Shallows Covenant” with an entity called the “Great One” in the Holy Land.
But even with just this “Shallows Covenant”, if I’m within the distance of their ability… It would be impossible to go against their orders…!!”
Gaban: “What a queer power.”

Shanks explained Gaban that he revealed his true self to Harald when they were together away from Mary Geoise, so they become friends. We can see a panel of that moment with Harald saying to Shanks “l knew it!! You are from Red Haired Pirates, right!?
Shanks said that Harald believed that if he joins the “Knights of God” Elbaph will finally join the World Government too. But that also means Harald must sign a higher covenant.
Gaban: “And is that trouble?”
Shanks: “By forming that new covenant, the “Knights of God” gain “superhuman strength” and “immortal body”. They are also given the power to generate an “Abyss” to transverse over great distances. In return, the Great One’s voice will follow them to world’s end. No matter where they are, they won’t be able to go against their orders…!! Harald won’t be able to say no to them anymore!! And I sincerely doubt those greedy people will still keep their promises then…”
Suddenly, Shanks and Gaban sensed a terrifying Haki coming from the Aurust Castle.
