The Irish goddess of war and fate, The Morrigan can whip soldiers into a fierce battle frenzy.
Your prompt is THE MORRIGAN.
The battle rages
In the chaos a crow flies
Over the victors
She can appear as a crow, presaging victory, but if she is seen washing your clothes, you are fated to die.
Black crow, death's omen,
War queen, the mustering hosts
Vie for your favor
Flicker of a raven's eye
whistle of a speartip
the next life has come for you
