Queen Avarosa.

Freljord was once ruled by humans. They were led by three sisters; Avarosa, Serylda and Lissandra. The Frozen Watchers approached them offering gifts, magic and immortality in exchange for their services and loyalty. Lissandra became the Seeker and voice of the Watchers, secretly betraying her sisters in exchange for her masters' power. Their people were forged into weapons and titled the Iceborn. They served the Watchers willingly at first, winning them a vast empire and building them the fortress now standing over the Howling Abyss.

In time Avarosa grew tired of their servitude and united the Iceborn, rallying them against their masters. The final stand against the Watchers took place on the bridge crossing the Howling Abyss. Many Iceborn died, but in the end the Watchers were overrun and thrown howling into the abyss, giving the crevasse its name. An Iceborn was chosen to guard the place in case the Watchers returned; Avarosa encased Greyor in ice so his spirit could stand vigilant eternally, sounding the horn if their former masters returned.

Lissandra engineered the death of her sister Avarosa, the true queen of Freljord, although what transpired is known only by the Ice Witch herself. She was buried beneath a cairn with her true ice bow. The grave was marked with a single rune: Avarosa. This grave and legacy would later be discovered by her ancestor and play a very important part in shaping the current Freljord.
