The Voidsea is an elusive and dangerous region that lies within Lumen. The Voidsea covers the surrounding sea of the Luminants and will appear when you sail too far off from the surrounding islands. The Voidfog within the sea can cover vision, making navigation difficult. You may also experience illusions with time since the Voidsea is nothing but a void.
The voidsea has an inherent connection to The Weave / The Depths and Drifting Fragments as It has a tendency to consume or spit our pieces consumed prior.
