Queen of Souls: La Calaca

The name's Mictecacihuatl but everyone in the underworld just calls me Mic. I rule Mictlan as the Queen of Souls and my sole purpose is to guide and protect my people. Every year, I navigate the three most important days of the year: Halloween, el Dia de los Inocentes, and All Souls Day. The humans celebrate Halloween on one night but unbeknownst to them, it really lasts until Nov 2nd (also known as Dia de los Muertos and the most stressful time of my year). As the veil thins by midnight of Halloween, the gates of Mictlan are opened and the souls of children are released back into the land of the living to be with their loved ones. But this year, when the souls of the children fail to return by midnight of el Dia de los Inocentes, I am left with no choice but to take off to the land of the living to retrieve them. If I fail to retrieve them by midnight of All Souls Day, they will be lost forever! Who took them? Can I find them in time? Or will their souls be doomed to being shredded by the Soul Eaters?
