Caelum’s Light is a holiday celebrated across the Relief. It marks the beginning of a new leap year and the anniversary of Caelum’s ascension. Chromatic rays illuminate the fringes of a solar eclipse on the first day of Adventus every four years. The light is believed to be a blessing from Caelum, the colours representing the pride or shame he may feel for his people at the leap year’s end.
Since the arrival of the earthmote Nox in 92 PO, it is believed that a new earthmote appears somewhere on Fio during every Caelum’s Light. Scholars believe that this is the result of Fio aligning with a planar portal created by Caelum when he ascended to divinity. Earthmotes may come from anywhere in the multiverse. They vary greatly in size and biome and can be deposited anywhere on Fio. Most earthmotes are uninhabited chunks of land which may house valuable minerals. On the occasion a populated earthmote arrives in the Relief, the Church of Caelum are the first to extend a hand of welcome and help reorient newcomers.
