Babylon 5 Wars: Showdowns-7 (2002)

"This book is an ideal companion to the League of Non-Aligned Worlds-2 supplement (BW-107). It includes new ships, rules, officers, improvements, technology, and scenarios for the races in League-2, such as: new Hyach specialists, special Grome railgun shells, elite officers for a dozen races, and more! Ships include the enormous Cascor Qoccata Supercarrier and flexible Ipsha Scout Wheel, plus OSATs and bases for every League-2 race and a dozen other ships and units! As a special bonus, Showdowns-7 includes an entirely new race never before published: the Yolu! Highly advanced, the Yolu avoided the previous Shadow War. They are slow to anger, but extremely dangerous when provoked...you'll see why when you get a look at their frightening ships and powerful technology! "
