Who do toi think got glacière powers: Nico ou Hazel?

Nico. But if Hazel could control mercury.....

Nico's powers are WAY better!
PS: Not that I don't like Hazel's.

nico because controlling the dead and shadow is WAAAYYYY glacière than finding underground tunnels and making cursed gems appear when your nervous

Hazel because toi could be RICHER than Bill Gates

ofcourse,hell is better than cursed riches.so, i go for nico.
