Synopsis
The issue opens in space with a view of the Glasshouse, a large spacecraft with what resembles a huge sword & scabbard pushed through it. This is the home of Myrddin and his Twilight Court.
Inside bright Lancelot (the Star) spars with merry Galehaut (the God) watched by Bedivere (the Engineer) and Bercilak (the Construct) (who doesn't speak but is still understood). Bedivere comments that Galehaut always lets Lance win, but she'll never let her know that. Galehaut suggests she and Lance go sample some of Bedivere's hidden brew, but the Star only has eyes for Artur (the King). However he, whose frail body is trapped in soul-cursed armour of Chthon, pines only for Parsifal (the Icon) the perfect knight training alone, but he daren't admit his feelings. The commentators are joined by Mordred (the Witch). Bedivere compares his ability to see how things fit together with her ability to see how they come apart. She tells them that Myddin is sending them against the Avengers.
Now we pick after the end of last issue where we saw the 7 members of the Court arrive in the orbiting Impossible City to confront only Scarlet Witch and Vision. Vision had been standing alone against them (off-panel) before Wanda Maximoff joined him. Now Artur suggests they fight no more and the Avenger duo just hand over Kang The Conqueror. Scarlet Witch casts a spell at them but it dissolves before it reaches them because Mordred disassembles it. Vision sends a blast at her from the solar jewel on his brow but Bercilak diverts it with a space warp. The King suggests surrender again - there is no dishonour when 2 face 7 and the man they defend is a villain. The synthezoid says that the Avengers currently have need of Kang so they will not give him up. Wanda reminds him that the other Avengers are trapped by Nightmare. However she adds that she has a plan to rescue them but it will take time to work, so they must stall the foes.
The Avengers' nightmare is that the Earth, the universe and reality are all unravelling and they can't stop it. Thor sees Asgard die, Iron Man Manhattan, Black Panther Wakanda, Captain Marvel the Impossible City and Captain America (Sam Wilson) Washington DC. But Nightmare detects SW mentally contacting the Thunder God and telling him he's in a dream created by Nightmare. He is angry because while the others are mortals who are always at the mercy of their dreams, he as a God is 1 of the dreams that they are at the mercy of. He calls down the lightning and shouts "Avengers assemble" to wake them up.
In mid battle Wanda tells Vizh that her plan is working. She is casting spells so quickly that Mordred can't dispel them all. So Lancelot attacks her with her twin blades but SW conjures up a flaming axe to counter them. Until Galehaut fells her with a mighty punch. Meanwhile Vision fights Bedivere, alternating between diamond hard and intangible, and eventually breaks his sword and smashes him down. Mordred asks Parsifal why he doesn't join in, but his sense of justice prevents him from getting involved in such an uneven contest.
The other 5 Avengers now know that they are in Nightmare's Realm. Their captor confronts them and claims they can't escape unless he lets them go. He claims to have been disrespected by Jean Grey and General Strange, and as a Fear Lord he deserves respect. So he'll let them go if the admit that he's beaten them and surrender. Panther, Marvel and Iron Man declare that Avengers never surrender. But Thor laughs and says that his obligation to help Vision and Wanda is greater than his pride - so he surrenders on behalf of the others.
Vizh and Wanda are severely beaten and Artur asks them again to hand over Kang. But then the other 5 Avengers appear to stand between them. And Parsifal smiles because now the scales are balanced.
