OBSIDIAN ISLANDS | Leader House
Riddle Name: Upon Typhon's Crown
"Stand atop where leaders dwell and you will see my isle. Typhon's Revenge is where I am - come visit for a while. Scale the mountain forged of fire, for at its peak I sit. But fear the smog and doom and heat, for they will test your grit."
It's on a balcony high up at Leader House.
