Coyolxauhqui
From Tardis Wiki, the free Doctor Who reference
Coyolxauhqui was the sister of Huitzilin.
She formed an army to overthrow her brother. Their uncle Quauilticac informed Huitzilin of his sister's plans. He used the Xiuhcoatl to destroy her army, then fed on her life force, killing her.
She became the inspiration for the legend of the goddess Coyolxauhqui. (PROSE: The Left-Handed Hummingbird)
