The Siegebeast was a large creature that has been enslaved by the Locust Horde, and turned into a catapult-like machine. They were known to be used by the Locust during their pre-industrial era and were reintroduced into their armed forces after the flooding of the Inner Hollow. To operate as a catapult, the creature is forcibly strapped into a war machine, with its limbs continually bent back so projectiles can be launched at enemy positions. Cole comments on how the "turkey" is very accurate at destroying targets.
