Bichura
The Bichura is a small, half-human sprite gathered out of the residue of spent spells — a weak, mischievous, and harmless thing, of the kind the Franks would liken to their pixies and their sprites. It can slip from sight altogether, or make itself as good as invisible.
One such Bichura tried its hand at Sidra's pocket; she slapped the little fingers away and the creature vanished on the instant. Being of a kinder temper, she then begged the unseen spirit's pardon and set out baklava for it, which the thing lifted of its own accord and bore off into the air. It was called a "freaky little guy," and reckoned, when glimpsed at all, no better than invisible.
Later the same Bichura flung a stone that caught Merrow full upon the head and dealt him a heavy hurt; and a later stone from the same hand went astray and struck Jean-Zera in the back of the head.
