Yaszen is a male human skyknight who ascended through the ranks based on bravery and strategic thinking. He is now commander of the forces at Horizon Military Academy as well as its superintendent. Aurelia believes that to create the perfect Boros society, the guild must target the young, so while the other military branches have their own training centers, Aurelia has intentionally made this the flagship of their educational efforts.
Yaszen has established watches and outposts in outlying districts. He has expanded the mounted divisions and encouraged the breeding and training of rocs and griffins. Almost all the Boros's handlers and riders of flying mounts are now based at Horizon. Under Yaszen, at least ten squadrons of skyknights are patrolling the skies at all times.
