Berserk v1.

In days of old, when battles raged
A warrior emerged, his name etched in the sage
With axe in hand, he charged into the fray
Unleashing fury, his enemies would slay
His name was whispered, in awe and in fear
As he stormed the fields, his legend drew near
With every swing, his axe bit deep
Leaving none standing, his power to keep
He's the berserker, with axe of might
Unstoppable force, in the heat of the fight
His roar echoes, as he takes the field
None can stand, against his battle yield
In the heat of battle, he finds his strength
A fury that burns, a power that length
His axe slices through, like a deadly dance
Leaving his foes, in a bloody trance
His legend grew, as the battles won
His name etched in history, forever to be done
The berserker, a hero of old
His axe, a symbol, of a warrior bold
He's the berserker, with axe of might
Unstoppable force, in the heat of the fight
His roar echoes, as he takes the field
None can stand, against his battle yield
Would you like me to elaborate on any aspect of the song, or perhaps create a backstory for the berserker warrior?
