Perun's Disasters:
Lightning Storm Vahocci: 1d20=14
Lightning Storm Valkyra: 1d20=13
Earthquakes: 1d20=3
An incredibly potent lightning Storm forms over the approaching battlefield. Thunderbolts strike amassing troops. As the conflict between Vahocci and Valkyra reaches it's climax, it is clear that both are at risk of being struck by lightning. (+2 death roll maximum for both)
The earthquakes are mild on the other hand, killing some but not severely impacting the world.
Vahocci's Host vs. Valkyra's Host
3d20=11+11+15
3d20=9+2+16
As the two hosts clash, Vahocci's host slowly starts gaining an edge. After the collapse of Valkyra's central front, Vahocci's men unleash a slaughter. Just before his men manage to corner Valkyra herself, her army reorganises itself, barely being able to keep Vahocci's Moss Trolls away. The front is bound to collapse at any time, leaving the Goddess more vunerable to Vahocci's onslaught. (+1 death roll maximum for Valkyra)
Vahocci vs. Valkyra
Valkyra: (=<5 death) 1d20=3
Vahocci: (=<8 death) 1d20=5
oof
An epic battle emerges. While trolls and angels fight around the great Goddess, thunder and lightning illuminate the world. It is said that Valkyra's front held the barely defensible line for three nights and three days, as the battle between Vahocci and Valkyra continued. These two battled for three days, dodging, striking, bleeding, screaming, charging and many things, spare for resting. In the end, with an enormous light, Vahocci unleashes his Godkiller technique. Valkyra is seen, shocked, angered, life leaving her eyes. She falls down, but not before lashing out to Vahocci and cleaving him in two.
The Goddess Valkyra has died at the hands of Vahocci the Godslayer, who does not live to see his victory.
After the death of the Goddess, Valkyra's line collapses, and Vahocci's enraged host kills her soldiers down to the last man.
This one was pretty rushed, please notify me if I've forgotten anything.
