Kafter

"'Many of the Löwa troops... puffed idly on knobby wooden pipes, exhaling clouds of curly, greenish smoke.'" "—The Sword and Its Servant"

Kafter were  fingernail-sized beetles that burrow into dead wood. They were harvested by the Löwa and dried out with salt and compacted into dense beads.

Kafter were kept in barrels until being crushed into a sticky resin and smoked in pipes. They were sometimes eaten, but were said to have a taste like rotten onions.
