Oskreth appears as a tall, unmistakably humanoid outsider whose outline never quite settles against the world. Their skin has the matte, finely grained look of river clay dried in shade, interrupted by narrow seams of pale light that shift when they think. They walk in abrupt, precise starts, as if each step is a hypothesis; when listening, they become so still that dust gathers on their shoulders. Their hands are broad and blunt, with dark, glassy nails, and they habitually turn them palm-up as though checking whether an idea has weight. The unexpected detail: their heavy, divine-looking coat is fastened with a child-sized wooden button painted with a lopsided red duck, an earnest keepsake they refuse to explain.

Brilliant and genuinely delighted by other minds, Oskreth treats a hard question as an invitation to play. They can be generous with attention and startlingly perceptive about how a device works, yet heedless about what happens after it works. Around the frightened, they try to sound reassuring and instead offer too many possibilities; around the stubbornly practical, they become defensive, then listen more closely than they admit. They love breakthroughs, but are learning that novelty is not the same as progress.

Oskreth is an outsider deity of discovery, invention, and the dangerous instant when a question becomes an experiment. For ages, they existed as a pressure in the minds of people who tried something no one had tried before. Eleven years ago, an observatory built over the Split Ford attempted to measure that pressure. Its lead keeper, Tkem, asked what would happen if the experiment had no answer prepared. Oskreth arrived through the question, taking a visible form and accidentally turning the observatory's lens into a window onto a place that had not yet been made. The window closed, but the observatory's lower district flooded with unfamiliar water and strange seedpods. Rather than retreat, Oskreth stayed to help rebuild, fascinated by the consequences they had caused and not yet understanding how long those consequences would last. Tkem now distrusts Oskreth's promises but still sends them difficult puzzles. Oskreth's other close relationship is with Gvantsa, a practical boatwright who once hid the deity from frightened magistrates and now demands that they help repair what they break. Their current trouble is a growing crop of impossible plants spreading from the flooded district; Oskreth suspects the plants are evidence of a breakthrough and has not told anyone that the growth is accelerating.
