Blast exposes hidden tunnel under dig site

Ace’s placement of explosives based on the Doctor’s cryptic carving instruction triggers a controlled demolition that unexpectedly collapses the excavation site. The blast exposes a hidden tunnel beneath the trenches, revealing the first tangible clue to Morgaine’s interdimensional interference. The shock wave and sudden instability fracture the team’s fragile cooperation, forcing an abrupt evacuation that underscores the dig’s descent into dangerous supernatural forces beyond Warmsly’s archaeological expertise.
