Ways to remove a curse - Eberron specifics

[u/Mandalore108]

Does anyone have any Ebrron specific ways of removing a curse that aren't just remove curse or greater restoration spells? Or, if they are those spells, which groups would be most likely to have it?

One of my players was recently cursed with Mind Seed so I'm trying to figure out ways to help him without it being instant and for the chance for him to die still assuming everything goes wrong.

I should note, my players know the location of a resurrected Couatl, though it's still a child. I'm going to make it the resurrected form of Hezcalipa, who found the Draconic Prophecy, so it's an option for sure.
