Warcraft Legends Vol. III is a collection of short tales, including the continuing story of Trag Highmountain, first seen in the Sunwell trilogy. Also included is the story I Got What Yule Need, written by New York Times bestselling author Christie Golden, and The Thrill of the Hunt, a story involving Hemet Nesingwary, one of the better known NPCs in game. The Legends series is one of the better ones out there, and at $5.99 for 160 pages worth of manga, it's a good deal.
Also released this month is the second book in the class series, World of Warcraft: Mage. This stand-alone story tells the tale of Aodhan, an apprentice mage whose dreams of making it big as a spellcaster are suddenly and violently interrupted. This volume delves into the story of Aodhan, but it also sheds a little light on the conflict between the Blue Dragonflight and the Kirin Tor highlighted back in Wrath of the Lich King. Like the other manga available on the app, Warcraft: Mage is also a steal at $5.99.
All titles are available for purchase through the Cryptozoic Comics App, and the app itself is free for download via iTunes. If you missed any of the manga releases, this is an excellent way to pick them up.
