Mayahuel

Mayahuel is a crazed prisoner, obsessed with the "Master of the Moon" (which is actually Senex Proxy). Gets skewered by debris when the chopper that Senex Proxy brings down crashes on her. Spoiler!She continues to narrate the battle between Ergo and Senex Proxy which follows right after, and draws her last breath after Senex gets defeated.
