Twelve Jackals: Illicitum Book One - Illicitum 2nd edition

In a divided land where rival factions struggle to gain control using the unique talents of their respective realms, Rakamai and people of Kala curb their use of magic, because to do otherwise steals years from their lives. But when a new alliance turns into a bloody betrayal and threatens open war, Rakamai vows to get revenge and secure the future of his people. To do so, he'll need to fully embrace the magic of his people, and bring his own considerable powers to bear. After all, a short future is better than no future at all.
