Jorm's Ambush is the fifth scenario in Conquest of the Underworld. While trying to reach the next level of the Underworld, Tarnum discovers that Jorm has sent his armies to slow him down. He's also built barriers in front of the gateway to the next realm, and Tarnum needs to find out how to pass through. Tarnum learns that Duke Deezelisk was blinded years ago, and would likely give up his underling Jorm if he was given the Pendant of Second Sight, which would cure him.
