Extra-dimensional storage spaces woven into wands, staves, and rings — a mage's bag of holding, but anything living put inside comes back dead.
A hoxter pocket is a small extra-dimensional storage space anchored to a physical object — a wand, a staff, a ring, or even a seal. The caster can slip almost anything into it: weapons, supplies, prisoners, entire laboratories. They are the working wizard's bag of holding, and every serious warmage carries multiple.
They have one universally known limitation: anything alive that goes in comes out dead. Taren spent months at Castle Saleisus trying to figure out why — reanimating dozens of chickens for the experiments — without ever producing a definitive answer. The effect is reliable enough that hoxters are routinely used as stasis caskets for captured enemies: a Nemovort placed in a hoxter wand comes out a lifeless corpse, which is exactly where a necromancer wants them to start a re-animation.
Dranus packs his entire laboratory into hoxter pockets in a new warstaff when he departs for Moros; Atopol used them to smuggle looted Nemovort vaults out of the Battle of Olum Seheri; the Sevendor household keeps whole cellars' worth of supplies hoxtered away for emergency.
