Mortum Caelum
The world of Mortum Caelum keeps time in layered ways: lens that divide the days and nights, months that tell the story of seasons and trade, and solstice rituals that reset the year. Explore each system interactively and see how celestial patterns shape every season.
Lenic Cycle
The lenic cycle took shape in Thalen because the land itself divided life into two distinct modes. Night pulls the mists up from the Ioma until the world narrows to a few lantern-lit steps, and day draws them back again, revealing the roads, markets, and river paths that make public life possible. Rather than treat day and night as opposites, Thaleni people learned to see them as one continuous motion of concealment and opening. A len became the natural measure of that rhythm, a full turn of privacy and community, and the twelve-len week formed around the dependable pattern of inward nights and outward days.
Historically this pairing formed because sunlight was never the guiding signal here. Mist decided when one could travel or speak broadly and when one must stay close, and this daily contraction and widening shaped every aspect of Thalen’s social world. Over generations this pattern intertwined with religious and philosophical thought, reinforcing the belief that all things come in linked states: what can be shown and what must be kept, what stands in the clear air and what moves through the fog, the communal face and the guarded self. The len became both a practical unit and a cultural truth.
The broader year follows larger pulses of travel, trade, growth, and rest that crest with spring floods, crest again with summer markets, and then contract into the fog and cold. Luthane, the brief solstitial week, sits outside those cycles as the Days Between, a pause where vows are renewed and accounts are rebalanced. Yet it is the daily breathing of the mist, held in each len, that shapes how the people of Thalen actually live inside that year.
