Traveller

Yegor Rajewski is a stuntman. His destiny is to wander the world in search of the key pieces. If he collects it all, it will give him power over the portals, but for now they are spontaneous, appearing whenever he wants, so he falls through, flying to another world. All he has is a chimera servant and a magic dagger, a soul-consuming dagger. And waiting for him are worlds of which there are many in the universe, magical and technological, post-apocalypse and far space, populated by humans and creatures, elves and orcs.
And in each of them, danger awaits Yegor - because he is a Traveller.
