J.R.R. Tolkien> The Lord of the Rings
Durin's Crown is a constellation of seven stars that resemble the Plough or Great Bear. It is the symbol of all of Durin's line. It was first seen, reflected around his head, in the Kheled-zâram by Durin. From then, the reflection of Durin's Crown could always be seen in the Kheled-zâram, even in the daytime.
It originated as the first stars made by Varda to welcome the coming of the Elves. It was placed in the northern sky as an open challenge to Melkor.
