By-Tor - Knight of Darkness, Centurion of Evil, Devil's Prince By-Tor in defeat retreats to Hell. Snow Dog is victorious. The land of the overworld is saved again. So clearly he's the bad guy here. I mean he had ambitions of leaving hell (across the river Styx) and doing some evil upon the overworld. Snow dog stops him at the gate (who may not be the good guy cause his eyes were shimmering with hate after all.) So then why is By-Tor the GOOD guy when he fights the Necromancer? Being the Necromancer, did he summon By-Tor who he could not control and By-Tor defeated the Necromancer (whose wraith flew away to darken other lands.) So By-Tor perhaps helped these three travelers unwittingly - just a summoned demon who the necromancer could not control? Did the Necromancer loose the Knight of Darkness on the overworld after all despite Snow Dog's earlier victory? Are these stories reversed chronologically? Perhaps By-Tor was summoned by the Necromancer, then defeated by Snow Dog?
