Shimmering Fields
The promised paradise after the world ends. The faith of the Two-Headed Basilisks teaches that the road to salvation lies through mortification of the flesh — the apocalypse must be met with eyes wide open. Suicide is sinful cowardice. Only then can the soul pass into the Shimmering Fields.
The death-obsessed cultists encamped beside the Death Ziggurat seek the Fields by other means — by finding the keys to a golden afterlife wherever the necromantic vibrations of the dying world betray them. They pursue salvation without doctrinal approval.
The Basilisks demand offerings such as "eyes that have seen the Shimmering Fields" — implying that some return from a vision, or that such eyes can be cut from the dead.

What the Fields actually look like, whether the Basilisks themselves know, and whether their existence is canonical or a comforting fiction is unwritten. The orthodox cult denies suicide as a means of entry but King Sigfúm the Kind commits exactly that — heresy from the Inquisition's view but apparently sincere belief.
