Queen of Tiwanaku

The Queen of Tiwanaku was the leader of the ancient civilization of Tiwanaku. Entombed in Paraíso, Peru within a crystal, her tomb featured a stone replica of the legendary sword Excalibur. An artifact called the Wraith Stone was used to protect the entrance of her tomb, with its Unknown Entity killing any trespassers.

Background History
As it can be read on the tomb's entrance, the in-game myth says she was the daughter of a King, lost an raised by a warrior and later crowned queen by a shaman. She used the god Viracocha's staff, found in lake Titicaca, to lead her people into an era of peace. She died shortly afterwards, when a power struggle broke into her reign.

Trivia

 * She has a further connection to the Wraith Stone other than its use as a protection mechanism in that its design appears engraved on her crown.
 * Seeing as its image appeared engraved on the wall and had an ornamentory copy by her remains, the staff featured in her myth can be safely assumed to be the same artifact as the sword Excalibur.
 * Knowing this, it's possible that the Queen wielded both the Wraith Stone with its creature and Excalibur at the same time, explaining her raise to ruler of her kingdom.
