Lighthouse Remains

On a strike of granite unfathomably sharp, the bottom half of a lighthouse has been worn from an incisor down to a stubby circular shape over the slow course of time. It does not look on a sea, but instead from its outpost, on an admixture of sand and muck, surrounded by head-high grasses uncommon to the area.

Deeper: Something beautiful is being reduced to nothing. In the loam about this white molar, pale, soft shell-less chin crabs lay their roe. They mulch the smooth stone of the former lighthouse, secreting lyme-filled excrement, perfect nutrition for the huge heads of ryegrass around.
The children of these crabs hatch actively and so the surrounding blend of swamp and dune is flush with the excitement of prey animals being hunted.
Stitch Shen Instance has built herself and her paper cren a roof in the ever-shrinking tower. The cren can take messages to and from the remainder of Instance's fellow historians and each week, one of its four mates will flap down into the opening with news on its heel.
The cren and her siblings spend the bulk of their time gobbling up tiny crabs or standing on the fallen walls that now constitute Stitch's bedroom beneath the stars at the highest parts of the remaining tower.
Stitch herself however is in the process of understanding the stickcharts she has collected inside, straight reed maps that showcase the currents and depths of the old sea. Her book which she keeps in five neat volumes, a sixth in process, is called 'Gone Now, A Seafaring Aristocracy' and her knowledge of the times before the Silt-Salt Sea is second to none, even among her own small cadre of historians.
She is an ensorcelled iron golem and so the bulk of false knowledge and rumor she has heard is exuded as rune-laden slag about the home—mounds of rumor—while the books themselves are made of thin hammered-copper sheets. Her sense of truth is unerring.
In d4 weeks after any initial visit, the second of the historians will replace Stitch, something like rotations in the medical field. It will study the lightning flashes and dire comets that blaze more frequently in the skies above C-36 than anywhere else in Corrhéo.
