Valacirca

Valacirca (Quenyan for 'Sickle of the Valar') is a star constellation in the heavens of Arda.

It was created by Varda just before the Awakening of the Elves as a warning to Melkor of his eventual downfall.

Other Names
It was also known as the Seven Stars, the Sickle and the Wain (by the Hobbits), and Durin's Crown (by the Dwarves). Today it is comparable to Ursa Major or the Big Dipper.
