Planes of Etera - Michael Chatfield

Dive into the relentless tides of the Water Plane of Etera, where survival means more than keeping your head above water.
The Four Horsemen, led by Desari, seek refuge and aid in the Water Plane of Etera.
She reunites with Irshon, an elemental ally from Desari's past, with vast knowledge and power. Though Limos remains out of reach, his wares and information kept from them when they need it most.
With no way to summon Limos, the group must embark on a voyage across the plane's seas to a planar convergence point. Only there can they pierce the veil to the material plane, to summon Limos once more and locate Ilus.
As they navigate through the turbulent waters, with powers unknown watching them. They'll have to learn to trust one another—and possibly become a true team.
