Khaine vs. Skarbrand

The Greater Daemon's owm weight drove it down the Suin Daellae's haft, impaling it through. Still the Bloodthirster fought on, hacking at the Avatar's iron body with its flaming axes. Each blow caused a grievous wound, but it did not fall. Flames of pure rage Toared around the duelling giants. The conflagration grew so fierce it consumed them completely. The lesser Daemons rallying for a last stand around their leader were burned away to nothing, and those Aspec Warriors that did not scramble clear were turned to ashen corpses. Lathriel ran, faster than she had ever run before, into the fight. Fighting against the heat, she hurled three runes of warding at the shattered gate to the Daemon-haunted webway beyond. The protective psychic symbols were pulled into place as if by hidden magnets, sealing the tunnel from invasion. Before beginning the arduous and soul-draining work of sealing the gate in earnest, Lathriel glanced back, hoping against hope to see the Avatar triumphant. She saw only flames, and a pool of molten iron.
