The description comes from the publisher:
The ribbons of Aler still hang over Grombelard. Another War of the Powers is coming inevitably. Today, tomorrow, and maybe in a week, somewhere among the peaks swamped by wind and rain, the enemy’s strength will come to life. The Heavy Mountains will burst from blows for the second time in their history, they will crumble, burn …
Each land has its legends. Among the gray rocks, in wet and dark caves, one sings about the King of the Mountains, the invincible giant knocking down his enemies with the sheer power of his gaze. About his faithful companion, the great cat-talker who showed respect to his enemies. About little Armektanka, whose destiny was to die in these mountains, yet she loved them with all her heart, and the Heavy Mountains loved her. About betrayal, the vilest possible and yet necessary. About sacrificing an entire species to change the fate of the world.
Yes, these are all legends. But without legends, Grombelard is just rain and wind.
