Castles + Magic + a few near by planets + probably a lot of furry species:
Two planets orbit the star
Sindovanya Andevarlon, 1.3 AU away from the star. Tidally locked, each planet appears fixed in the sky of the other, a mere 20,000 ish kilometers from each other. Days are about 6 hours long on each planet, and one the face facing the other planet, the middle of the day is blocked out by the opposite planet. On the far side, the unobstructed view of the galaxy fills the sky, with merely the sun and faint planets roving across the sky, ignorant of the behemoth hiding behind them.
One the first planet,
Zondoshinda Aroya, there lives three furry species. First, the
Zoleen, humanoid deer, living on a continent far away from the other species,
Aclend, and isolated for all but one strange crew.
The Remarkable Adventures of Varenda The Salty being the only tales of the Zoleen to make it to the rest of the world, the Zoleen remember, and prepare to meet their neighbors, and see this strange giant in the sky with their own eyes.
On the inner side, are the
Sanyadarishya, humanoid foxes that love adventure and invention. Living on
Ashoya, the Sanyadarishya met the
Airelsat first, mouse people who form large isolating clans in the countryside, and build large castles. Some are rarely great explorers, but more stay near home and are deeply connected to their home.
