The Night Star
Isla is not a world in the typical sense, but the shattered pieces of a once-whole planet bound together by powerful, ancient magics, forever adrift in space. As Isla itself does not orbit a star per se, its day and night cycle are instead ruled by twin celestial bodies, colloquially known as the Day Star and Night Star.
Umbra’iene the Night Star, circles the archipelago of Isla’s subcontinents once every 24 hours, completely blotting out the light of its sister star, Lumashe and allowing “night” to fall. Many myths and old wives’ tales surround Umbra’iene, the most common speaking of the demons that crawl across its surface, so many in number that they make the entire sphere black. To be born in the shadow of Umbra’iene is said to be an ill omen, and the particularly zealous will often drown children born under the Night Star.
While no stars dot the skies of Isla, the night is not totally devoid of light. Cloud-like silver strands of astral energy sweep in great tides in the Sea of Sky, brilliant while flowing and faint while ebbing.
