Oulla was born in the year 1371 after the Adventus, destined for greatness as the daughter of the high priestess serving the revered Snow Goddess. Raised from birth within the hallowed confines of the goddess's alpine temple, Oulla was tutored in all the mystic arts - from interpreting the ominous cracks forming in the sacred glacial ice to divining prophecies amid the hypnotic patterns of blowing snow.
Even as a young girl, it was evident that Oulla possessed an innate gift for walking the frozen paths and discerning the ethereal whispers carried on the winter winds. She delighted in wandering the temple's winding tunnels and secluded shrines, entranced by the mysteries contained within the hoary edifice's ancient, ice-sheathed stones.
It was on one such solitary vigil at just nine years old that Oulla followed her intuition down an unassuming side-corridor she'd never noticed before. Her breath was stolen away when the narrow passage unveiled a hidden crypt - within its rectangular confines lay a massive crystal ball, clouded and quiescent but unmistakably suffused with mystical energy. Beside the orb rested an ancient, leather-bound tome too engulfed in uncounted years of ice to discern its contents.
Oulla knew she was forbidden from these sealed sanctuary without her mother's permission. Yet she also sensed profound significance contained within the crypt's offerings. Resolving to investigate further, the daring young priestess-in-training furtively copied down a series of indecipherable hieroglyphs from the tome's elemental-blasted pages onto a tucked scrap of cloth.
Upon presenting her finding to the high priestess, Oulla was shocked at the elder pathfinder's sputtering outrage. She attempted to destroy the copied hieroglyphs, refusing to reveal anything about the crypt's origins or contents. Crushed by her mother's reticence yet still burning with unslakeable curiosity, Oulla began slipping away nights to consult the crystal ball and grimoire directly.
What she discovered within those hallowed pages proved nothing short of life-altering. They spoke of an ancient, titanic war waged at the very dawn of creation between the immortal pantheons and the abyssal, hell-spawn demons whose very existence threatened to unmake all of reality. Only through banding together and recruiting the greatest mortal heroes across all worlds could the divine ones finally repel the hellish incursion after eons of devastating conflict.
Utterly enrapt by these revelations of humanity's pivotal role in defending the cosmic order, Oulla became obsessively devoted to the teachings scribed in that eldritch manuscript. In her dreams, visions of heroic mortals battling unholy behemoths from the abyss with powers beyond reckoning began manifesting. The rush of being granted such sacrosanct knowledge simultaneously exhilarated and terrified the young priestess initiate.
On one fateful night after an especially vivid vision where Oulla witnessed a apocalyptic confrontation between the gods and demons, her consciousness was pulled into the astral plane. There, the towering, regal presence of the Snow Goddess herself appeared amidst swirling frozen mists. In that cosmic moment, the deity proclaimed Oulla as her newest Seeress - designating her as one of the paramount mortals tasked with divining the future paths to safeguarding the realms of existence.
From that luminous intersection, Oulla feverishly applied herself to imbibing every sacred teaching contained within that long-sealed crypt's grimoire. She became renowned as a fantastically skilled oracle, able to interpret the most subtlest patterns of ice, wind and celestial movement as visions into the tumultuous threads woven by the gods themselves. Word of the young seeress's preternatural abilities soon reached even the ears of the kingdom's rulers. Before the age of 30, Oulla took her place as the official royal seer and spiritual counselor to the entire realm.
Now wed to the current king following the tragic demise of his father, Oulla has become an indispensable bulwark against the myriad looming threats that seek to imperil the lands. From the warmongering gedun hordes massing in the Burnedpeaks to the return of the aboleth dread-harbingers presaging another exodus of the abyssal ones, it is the aging seeress's unshakable faith in the Snow Goddess's visions that continues steeling her people's resolve.
Oulla knows that her destiny - to bear witness to the coming apocalypse foretold in the eldritch grimoire's uphasings - is only just beginning to unfold. But she takes solace in the knowledge that it was that fateful day as an idly curious initiate that first set her feet upon this sacred path. And it is that same, unbroken sense of child-like wonder that allows her to greet each darkening omen not with trepidation or fear, but with a humble certainty that she will play her foretold part in the great war between light and shadow still to come.
