This supplement for the ‘Army Lists for the Forces of Good: Forces of Fantasy’ book includes additional background, Armies of Infamy, unique characters, new units, a narrative scenario, and new magic items for the Asur, the High Elves of Ulthran.
The background section of the book includes a brief history of the High Elves, some information on their outposts around the Old World, and a brief look at the colours and iconography of the realms of Saphery, Chrace and Lothern. As well as this, the book also has narrative section about High Elf forces attempting to rescue an Ambassador captured by Beastmen in the forests of Bretonnia. The narrative scenario that goes with the narrative part of the book, where the High Elves have to stop a Beastman ritual, does looks fun to play. All this lore is good, with the narrative part being particularly good, but I think there is at least one error where west and east unfortunately are mixed up.
The two Armies of Infamy included in the book are for the forces of Chrace and Lothern, and while I would have preferred one for Saphery or Caledor (my two favourite High Elf realms) they both seem good, with the Lothern one probably being my favourite due to the inclusion of the Skycutters and Phoenixes, two High Elf units I have liked since I first saw them. The new units in the book follow the usual pattern for Arcane Journal units with them being mostly themed around the two Armies of Infamy, and are often specific variations of existing units (Stom Weavers are alternate Mages, Characian Chieftains & Sea Guard Garrisson Commanders are alternate Nobles, etc.), veteran versions of existing units (the Lion Guard are elite White Lions) and more esoteric (often former Forge World) units such as the Merwyrms. All the units are good, however, with some of the alternatives being good conversion subjects. The two named characters are, of course, from Chrace and Lothern, and both of them are good. The first is Korhil Lionmane, the Captain of the White Lions, a nice character from previous versions of the game. The second a new character, Ishaya Vess, Sentinel of the Silent Isle, who is a good edition with some nice rules. The new Magic Items in the book are all good, with some I recognise from older editions (such as the Blade of Sea Gold), and some that seem new (such as the Staff of Solidity).
