Zeke Larson, newly assigned as a Demon Warden after time-traveling to ancient Drosa, faces his first mission, expecting to deal with minor threats. However, he soon discovers an ancient tree demon underground, far deadlier than anticipated, known for massacring a hundred soldiers in the past. As his team panics, a system alerts Zeke to the demon's threat and activates the Demonbane System, granting him a new ability called Bane Eye, which reveals demons' weaknesses. The episode ends with Zeke preparing to confront the formidable foe, his true test only just beginning.
