The Space Time Juggler – John Brunner (1963)
‘DUEL IN THE ARENA OF THE STARS
Andalvar of the planet Argus, king of an interstellar empire, was dead and fear ruled in his absence. The dread of a power struggle between the treacherous Andra, and “Black Witch,” and the beautiful Princess Sharla showered panic upon the people and threatened to crumble the starry realm to dust. But their powers were restricted to the present, and before either could sit on the throne, they would have to come to grips with the man from the future who held the destiny of the universe in his hand. His name: Kelab the Conjurer – THE SPACE-TIME JUGGLER’
Blurb from the 1963 F-227 Ace Double Paperback Edition
Set in the same universe as The Altar on Asconel this inhabits that uneasy space between SF and Fantasy.
Following the death of the King of Argus, Andra, ‘The Black Witch’ has become regent on this colony world which has in the main reverted to feudalism. Her older sister Sharla – missing for seven years and presumed dead – suddenly reappears to claim her place accompanied by Landor and the swordsman Ordovic.
Another stranger also arrives, Kelab the Conjuror, a man who appears to command magic and, it seems, is interfering in court business.
It would be giving the plot away to explain anything further as it’s a brief read which is well-written but suffers from a lack of cohesion between the slave-owning and sword-wielding society and the hi-tech elements.
There is no individuality to this society. It is set in the mould of every other far future feudal planet favoured by the likes of Lin Carter and his contemporaries, which somehow always has to include some monarchist system. The characters are stock stereotypes with little light and shade. There is a decent enough surprise and plot twist bit one feels this could have been a far better novel given some thought to the world building and some space to develop characters.
