Sibba
“sister, she who is”
sibb “sister” + -a “she who is”
Sibba (“sister, she who is”) is a 7-star constellation of The Other Sky, spanning 20° of the equatorial sky. Its brightest star is Pyrenureth, magnitude 0.18.
The story
The Braen hold that Sibba was a cartographer who gave away a name and was answered by everything, and was nailed to the cold part of the year. It is a figure of the winter, and its setting is the older marker for the end of that season. Pyrenureth, the red ember, is the knot; the remaining 6 stars are counted against the turn. Those who keep the old year name no child in the weeks it is hidden.

How this was made
Sibba was not designed. It was grown outward from Pyrenureth, the brightest star in this part of the sky that had not already been claimed by another figure, absorbing near neighbours until it ran out of them — which is, near enough, how the constellations of the real sky came about. Its name is Ilmenic, an invented agglutinative language: every name on this site decomposes into morphemes and can be translated.
