Thus, Mokosh did visit Veles and did confront him on the matter of the Horrors.

Demanded she that Veles did restrain his most wretched hounds and order them to cease attacking innocents, to cease all things except guard nature. He was to promise that if any of the Horrors shalt fall, having fulfilled its task, by the power of Veles, it shalt be released from its most grim service and cleansed of all filth, that Veles shalt accept it into his realm, and that it shalt never again be put into a filthy shell.

And Veles did agree, much to Mokosh’s relief. Howe’er, he did not reveal unto her that his power over the Horrors was frail, and the promises given did resemble a slippery rope harnessing a great beast – for there was too much of Air and Water in them and too little Earth. What he did put in motion he couldst not stop – and that was the secret of the Age of Misery.
