The world is in total darkness, moving slow and days are longer than years
(the planets rotates around the sun in 5000 earth days and rotates around itself in 50'000 earth days)
One day is longer than a humam lifetime. Nomadic tribes are constantly moving between total darkness and light to search for resources, they could live on the sun side all the time because the planet has a thick atmosphere and is really far from the sun, so heat is not a problem.
But a lot of vital resources are located in the dark of the planet so continuous journeys are needed to survive.
For young boys with no experience in traveling, they are gifted pet ravens which were trained by their fathers to locate the light even when in total darkness.
The raven could be on the other side of the world in the dark and will guide the boy back home.
Can ravens be trained to make sounds that boys can interpret as instructions on where to go or what to do? Because just following a black raven in total darkness is not easy.
Instructions such as "turn left" "turn right" "sea ahead" "we are on mountain" "storm incoming" "danger hide"
