Mnemopool

Mnemopools are elemental remnants left when bodies of water are violently drained, salted, or bound away. When a lake's spirit is fractured by unnatural means — a dam shattered by sorcery, a binding ritual, or catastrophic drainage — fragments of its consciousness can condense into small puddles that retain the lake's memories: shorelines, currents, the names of fish, and the cadence of storms. These fragments drift for months or decades, searching for conditions that evoke their old home. Local fishermen and marshbound hermits tell of Mnemopools gathering at springs and culverts, whispering to gulls and leading schools of minnows toward safe shallows. Scholars such as the hydromancer Archivist Maret of Sarnell Mire have catalogued their behaviors; Maret theorizes that if several Mnemopools find one another and a continuous water source, they can recombine into a full-grown aquatic elemental over years. The Conservers of the Delta take special measures when they find these puddles, seeing them as both omens of ecological harm and as pieces to be reborn if returned to a suitable basin.

A Mnemopool appears as a shallow, slightly shimmering puddle about two to three feet across when still, its surface roiling with ghostly echoes of waves and ripples. Within the liquid, faint shapes of reeds, pebbles, and a sliver of shoreline shift beneath the surface like a faded map. Its edges thicken into translucent tendrils when it moves; when disturbed those tendrils momentarily hold the silhouette of a splash. The surface reflects light with a cold, silvery sheen and occasionally flickers with a pale bioluminescent patch where a remembered fish darts. Scale: typically about the diameter of a small barrel or a large basin, waist-high ripples against a crouching human. Textures: slick, glassy surface with viscous, oily tendencies at the fringe; the puddle leaves faint damp footprints when it crosses dry ground.
