The Nemesis Moon

I have whirl’d with the earth at the dawning, When the sky was a vaporous flame; I have seen the dark universe yawning, Where the black planets roll without aim; Where they roll in their horror unheeded, without knowledge or lustre or name.

'Nemesis' - By H.P. Lovecraft

13 years and one day after the death of Torm at the hands of Vecna, a second moon appeared in the night sky.

No one knows why it appeared, and all attempts to divine it, its origin, its purpose, its mysteries, have all failed.
