Athena Minerva's Ragnarok

At the end of the many fabled tales of Saint Ingrid, was her own personal Battle of Ragnarok, a final combat of good (armies defending human life on Earth) versus evil (armies built to kill and eat human life).
It was after, as the legends go, Ingrid, (playing her role as Lachesis Valkyrie), had finally tracked down the evil forces creating all of the man-eaters of ancient mythology, called The Three Norns, forces which Valkyrie had always warned her devoted followers were tremendously more powerful than herself. After a quick exchange of words, Valkyrie "awoke the sun on Earth" in a surprise attack to end the parley, melting the villains and their stronghold in an event apparently similar to a nuclear explosion, which of course Valkyrie and her minions survived.
Interestingly, in a concept modern philosophers refer to as "meta", in Valkyrie's tales the narrators point out that all other myths and mythological creatures and gods were fictional until deliberately created by the Norns based on the earlier legends. Strangely, since Ingrid lived mainly among the Norse people, Valkyrie and her two sisters went by the names of the more exotic Greek Fates while the villains of her stories went by the names of the Norse Norns who (although not exactly heroes in Norse mythology) were thought by the Norse to be invincible forces of Nature which no man could even question. The idea of any heroine defeating such unassailable beings must have been as mindbending to the people spreading her legends as the thought of warping space was to the 20th century mind.
Most of the Norns' evil magic died with them, but the armies of man-eaters they had already created then reflexively grouped together to form a massive land army based in what is now Germany. Norse and Germanic trolls and jötunn giants and various twisted denizens from myths of Jötunheimr and the Unseelie Fey were intent on not only holding that land, but advancing to the rest of Europe if not the world (after of course dining on the human residents of the land they then occupied).
Valkyrie's allies from her previous adventures marched in to aid her in a cataclysmic battle that was said to stretch across a battlefield from one horizon to the other. Boatloads of Norsemen aching for a good fight, and Pre-Zulu South African warriors ready to show their mettle against the inhuman villains, as well as armies from Athens and Rome marched and began to fight in a coordinated effort without any previous contact with each other aside from the mutual acquaintance of Valkyrie and her berzerkers.
Only in modern times would the logistics of moving that many separate military forces in that short a time across so many unaffiliated kingdoms and fiefdoms be even remotely possible, but according to the legend, their loyalty and morale was so firm in the certainty they would save the human world, all other considerations of life were paused for Valkyrie's forces to make their way through.
Representatives from all the armies of humankind, the story goes, fought the invaders down into a tighter and tighter circle of land until reaching a stalemate. Valkyrie and a few of her berzerkers, (after a risky move to charge through the enemy lines and behead the largest of the giants), had been taken captive and held in the center of that circle, but no amount of loyalty nor strategy could bring the human forces to break through the fortified circle and rescue her. At that time, Valkyrie called down the last of the power from her magical ship, which earlier in the story had been noted to be parked in the sky, occassionally visible as an out-of-place star. A burst of sunlight and heat incinerated everything inside the perimeter and turned each body into lifeless ash and stone.
The human armies saw in the sky above them a falling star of flame and smoke separating into tumbling pieces.
Valkyrie and her closest followers had died along with the threat to all intelligent life on Earth, but the remaining alliance of nations of the two continents could then begin telling her stories, remembering the power of strangers trusting each other for a common goal and combining their forces.
The legend ends with the promise that Lachesis' younger sister, Clotho would someday arrive in another ship sailing among the stars when she would thaw out of a frozen block of ice and check in on humanity when it needed her most.

Some literary scientists suggest some 15th century A.D. tales of Joan of Arc may have borrowed ideas and scenes from the 11th century mythology of Saint Ingrid due to certain similarities. Alternatively, the heroine of France (at a young age as a peasant in Domrémy in northeast France) may have heard the tales of Saint Ingrid's military strategies and victories and learned some of her own strategies as a military leader from the myths.
