Book III. Bifrost (The Rainbow Bridge) - March Of The Gods

Odin opens the doors of the hall
Rises every warrior to the call

The gods are marching again
Across Bifrost
Valhalla's heroes of death
All cross Bifrost

Heimdall sounding the horn Gjallir
Asgard's calling to war for the earth
Mighty hammer of Thor Mjolnir
Lightning's magikal lord of thunder
