_The beetles wore golden bridles and carried huge leather sacks of stone and guano. They marched without stopping; dozens, even hundreds, bringing fresh earth to the white-fungus trees of the great forests. Their claws skittered with a sound like horseshoes slipping on stone, but their multiple legs ensured they never fell. The air around them singed the nostrils with the taint of acid._ **Beasts of Burden and War.** Carrion beetles are powerful beasts of burden with strong jaws and the ability to both climb and burrow. With a wide back, serrated, spiky forelegs, and a narrow head, the carrion beetle is too large to ride on very comfortably although it makes an excellent platform for ballistae and howdahs. Its thick exoskeleton varies from drab brown, tan, and black to shimmering blue green, purple-green, and a highly prized yellow‑orange. The largest carrion beetles make a distinctive wheezing sound when their spiracles are stressed; this noise creates a hum when multiple beetles run or charge on the field of battle. War beetles are often armored with protective strips of metal or chitinous armor fused to their exoskeletons, increasing their natural armor by +2 while reducing their speed to 20 feet. **Devour Fungi and Carrion.** Carrion beetles rarely gather in groups larger than a breeding pair and a small cluster of offspring in the wild. The domesticated varieties travel in herds of 20-40 to feed on fungal forests, scavenge battlefields, or devour cave lichen and scour sewage pits. The larger caravan beetles are always antagonistic. When breeding season hits, carrion beetles feast on the bodies of large animals. They are often found in symbiotic relationships with deathcap mycolids, darakhul, and related species. Many species in the deep underworld consider carrion beetles food and use their exoskeletons to fashion shields and armor (though their chitin is too brittle for weaponry). Purple worms are their major predators. Worms swallow entire caravans when they find the beetles within. **Domesticated by Ghouls.** Domesticated by the darakhul, the carrion beetles live a more complex life. They begin as simple pack animals, with the strongest being trained as war beetles. War beetles often carry ballistae and harpoons fitted with lines for use against flying foes. In late life, the beetles are used as excavators, scouring out tunnels with their acid. After death, their exoskeletons are used both as animated scouting vehicles (ghouls hide within the shell to approach hostile territory) and as armored undead platforms packed with archers and spellcasters.
