Reprint Collections You May Have Missed

I still need to catch up on recent Captain Britain collections, but these are also of interest:

Knights of Pendragon was published in the early 1990s by Marvel UK and presents a band of heroes recruited by the Green Knight and empowered by the eternal spirits that once empowered the Knights of the Round Table. This arc features an adaptation of Sir Gawain and the Green Knight as an ecological allegory. The collection includes two introductions by series writers Dan Abnett and John Tomlinson who comment on the genesis of the series and its development.

A more recent series, Iron Man: Legacy of Doom series as a follow-up to the Iron Man: Doomquest collection and presents Iron Man and Doctor Doom third (technically fourth if you count the Heroes Reborn books) encounter with Morgan le Fay and Merlin. In this series Doom secures Excalibur and seeks to recover its scabbard in an effort to save the Earth from an extra-dimensional threat.
