The Strength of the Storm

The ritual I must conduct is written on a scroll. To gain access to it, you'll have to break through the dark energies the fallen tidesages have placed around it, with the power of the storm. This relic can be used to pull purified power from the enslaved elementals. Not only will you be gaining the means to our end, you will ultimately be freeing these spirits from corruption. Defeat the enslaved elementals and then call their power into the relic.
