The Dagger (Onderon)
"The Dagger," a rock spire of imposing height, yet impossible to climb, was located on the southern edge of the planet Onderon. Situated at the base of this spire was a group of villages known collectively as Dox Piter. A famous battle unfolded there, pitting the beast Wodnakki against the Royal Guard of Queen Lina after the creature constructed its nest on the spire's summit.
