Sky and Seasons

The day and night cycle on Mundus is tied to the seasons.

Springrise is when the Sun rises in the West. It lasts for about 24 hours, during which time the paths to The Feywild are open. The skies clear of Winternight's clouds and the brilliance of the Arch can be most clearly seen.

During Summerday the Sun rises high in the sky, circling the horizon but never setting, bringing forth the great mists from the Ocean that is the Enclouding. The nearly constant daytime overcast lasts for ~1400 hours, and the climate is hot and steamy. The flora and fauna go into overdrive, making the most of Summerday before the next Winternight.

With Autumnset the Sun sets in the West and the Enclouding dissipates. Also lasting 24 hours, the skies again show the Arch, and the paths to The Shadowfell open.

Winternight is the long darkness, with lots of snowfall and, when the clouds dissipate, the Arch spans from horizon to horizon, causing perpetual twilight. Most animals migrate or hibernate, and the Undead emerge.

The Arch is thickest in the higher latitudes of Ishtar, although reports of distant traders say it is thin in the skies of Aphrodite. The Vigils are a grouping of bright stars which move across the night sky in intricate patterns.

The Sky Elves say Mundus is a giant sphere, and their Castelas follow the Perpetual Spring, the narrow band of Springrise between Summerday and Winternight which they say circles the world.
