It isn't always flies, ran. Sometimes it's wasps or moths or jewel-jaws. They don't bother me—much—because they never land, but they don't tell me anything either.
– Gari, To Ride a Rathorn, "Chapter IX: School Days", I
Gari is a Comanrandon cadet who has the Shanir ability to attract and command a swarm of insects. He does not appear to have any control over the kind of insects he attracts, but they are always all the same type and appear to reflect his mood and recent duties. Once he has them, he can't make them leave, and he once gets kicked out of the barracks because he's infested with termites.
↑Bound in Blood, "Chapter V: Fractures", III — "Gari and Mouse were in general bound not to individual creatures but to swarms,"
↑To Ride a Rathorn, "Chapter X: Battles Old and New", IV — "He didn't seem to have any control over what kind of insect he attracted, although they did seem in some way to reflect his current mood. […] The last time, after a particularly miserable work-detail cleaning latrines, it had been a swarm of stink-beetles."
↑To Ride a Rathorn, "Chapter XVI: Midsummer's Eve", I — " 'that Coman cadet Gari picked these flowers, but he asked me to bring them because he's come down with an infestation of termites. […] The master-ten of his house has him sleeping outside.' "
↑To Ride a Rathorn, "Chapter XXIII: Touchstone", II — "They careened through the great hall of Old Tentir, joined at the stable ramp by Gari on a raw-boned bay and a golden-green mare with rider. […] Out they burst into the morning sun, down to the New Road, then south toward Gothregor."
