Below Us The Battle! Traveling to England to search for their missing comrade, the Black Knight, the Avengers are stopped by the British division of SHIELD because they are carrying the Swordsman and Mantis aboard their Quinjet. Explaining that the Swordsman has reformed, they decide to grant him temporary amnesty while in Britain. Arriving at the Black Knight's castle, they find that it's protected by an invisible barrier. Their presence near the castle alerts the attention of Skol and his army of Troglodytes, a group of underground dwellers who were forced into living under the castle for centuries. They capture the Avengers and take them prisoner, where they are blamed for the barrier blocking their path as the Troglodytes used an underground entrance into the castle to steal food. After battling a giant insect, and fighting off the attacking Troglodytes, Skol surrenders to the Avengers. The Avengers however decide to help the Troglodytes out by making arrangements with the British government to aid these underground dwellers. With Skol's problems dealt with, and the knowledge that the Black Knight was taken from his castle by costumed beings, the Avengers leave England to continue their search for the Black Knight.
