- Kyo (Silver Axe) was given a devil fruit by Xebec (Moon Logia)
- It says if he masters fully the power he can control all moons surrounding the planet
- Harald knows a legend about a giant much bigger who used the sword on elbaph to cleave a moon, there used to be 8 moons
- The moon that was cut had the properties of sponge
- In Elbaph we see Imu telepathically talking to a Giant Elder, it's said that giant is 1000 year old, can barely walk but he looks huge, his name is Odin who cleaved a moon 900 years ago on command of a Mihawk ancestor from 850 years ago, apparently it was less impressive than cutting diamond
