John Daker knows no peace, and after having made, as Erekose, a VERY questionable thing (see The Eternal Champion), maybe serves him right. or maybe he was a pawn of Higher Powers in the Multiverse? He finds himself in a world similar to that of The Ice Schooner, but much more dreary. He is evoked as Ulrik Von Skarsol, and he doesn't find his summoner. Certainly it's not the lecherous, paedophilic Bishop Belphig, a man of unspeakable vices who rules as Lord Spiritual ( a not so veiled mockery of the Catholic Church, I think) a hellish City of Decadence. Bishop Belphig abandons him during a hunting expedition, where Daker is urged to find the Black Sword (none other than Stormbringer, says the dwarf Jermays the Crooked) Daker doesn't want no black sword, he only wishes to return to his Eldren love Ermizhad. He will find his summoner and learn more of the nature of the Multiverse and of Eternal Tanelorn; his ordeal will continue in The Dragon and the Sword.
The adventures of John Daker are a crooked, crazed existential metaphor that's pure Moorcock as its best.
