Dome of Crystal Seers
The Dome of Crystal Seers is a location within a Craftworld's wraithbone core, existing as a broad bio-dome littered with groves of tall wraithbone trees that reach out into space. It is here where the most ancient Farseers of the Eldar retreat to. As Farseers reach greater and greater ages, their minds become so closely linked with the Craftworld's core that their physical bodies simply grow dormant. Within the Dome, the eldest of seers gradually crystallize and take root, until they turn entirely to crystal. The Farseer's spirit is then preserved forever within the psycho-conductive Infinity Circuit.
