Toporkl
The Toporkl were Evenki reindeer hunters of the Sym, a left tributary of the Yenisei known in Evenki as Chirembu, wandering the swampy western edge of the Siberian taiga. A Mangazeya Cossack detachment reached the Sym's mouth in 1610, and the band thereafter paid the yasak fur tribute to the Russian outposts on the Yenisei.
