House of the Big Dipper

You can recognize this House by such signs. He is high, high on the Star Pine. Where the nights last for half a year and Aurora shines in the sky. Where on mothers night they tell their children stories about the bright warm Sun and the cold Lusha. About fiery sunsets and sunrises. About the sweet cloudberry in the emerald moss...
The only way to get there is through a spiral staircase.
Billions of stars circle around in a round dance and twinkle with frosty polar lights.
And inside the hearth burns and the windows shine with warm light.
