Kiralyn

From LSWiki

Wanders the Ebirian desert. Stupidly strong and fast in combat, striking a couple times every round without fail. Wields a scarabinium greatspear and holds the Seismometron artifact. Has a flycatcher familiar, but even if you kill it, it won't diminish her combat prowess all that much.

Sometimes, the sand worm eats her.

She certainly looks to be a Maiden of the Spear.
