Gallahas

"'And in his hand; a shimmering blade of silver and gold, laid in with the iron will of Jular's people. I knew at this point that it would be Him to deliver us of evil.' ~Excerpt of the Historia Rex Deus, by Brodiwen"

Gallahas
Gallahas is the sacred blade that formed when the Fire Emblem shattered, and said to contain part of Augustus' original strength.

Its power is without equal in Jular, and no demon could ever hope to stand to its fierce powers.

Gallahas is also a crucial part of the God-King Cycle. When the God-King dies, Gallahas is returned to the Temple of Kings and placed in the hands of the statue of Augustus where it is sealed with powerful magic. Only the raw strength of the inherited soul of Augustus could possibly hope to break the seal and reclaim the blade--and once someone does, it is the indisputable proof of their heritage.

A dark counterpart to Gallahas, colloquially referred to as "Dark Gallahas", was spawned upon Augustus' resurrection. It seemed a mirror image of the original blade, but lacked its true power.

On the Day of Demon's End, when the Emblem was shattered by Koen, both the original and dark versions of the blade turned to the stone from which they were once carved. They remain a permanent part of the Cave of Origins.
