Heroes of Durgeth:
Runa's Helm of Mitonsoul can crush foes up to 3 spaces away. Kaemon Awa's double attack and counterstrike sap the enemy's life force. Toxic Skin and Mind Shackle give Kee-Mo-Shi a decisive edge. Kiova's Gift of the Empress boosts the defense of her fellow Kyrie. Eldgrim's Overextend Attack gives him extra turns; if he destroyed, his spirit inspires his followers! 
Archers & Kyrie:
Einar Imperium: The highly disciplined Imperium squad adds the power of double attack to your army. And as Kyrie, their flying ability comes in handy for quick escapes over uneven terrain.
Shades & Orcs:
Shades of Bleakewoode: These goulish warriors take control of nearby Heroes with their insidious Soul Devour power. Their stealth Flying power enables them to travel quickly over uneven terrain.
They are two seperate squads, but the Zombies of Morindan can join forces to overwhelm the opposition. Their Horde Movement allows all six to move in one turn; and three Zombies can combine their attack dice to launch one massive strike. But their greatest threat maybe their Zombies Rise Again ability: when a Zombie defeats an enemy, a destroyed fellow zombie may rise again to replace it!
