Llamas Chapter 10 Review · 2:54am Oct 6th, 2015
In Llamas: a Drama Chapter 11, it is revealed that Discord was worshiped as the spirit Supay (the Inca god of the dead). Then the other god, the Aztec Mictlantecuhtli, the same spirit Urcu 'prays' to is mentioned. This spirit has yet to be revealed, but it will revealed along with Emperor Urcuchillay's treachery.
If you're too eager to get to that, here's a spoiler:
Mictlantecuhtli is really 'Grogar', a demonic goat with necromantic powers who was banished to Tartarus along with Tirek. It's revealed that Grogar escaped Tartarus along with Tirek, but chose to remain in the shadows until the opportune moment. Namely, when the Llama Invasion led by Emperor Urcuchillay takes place. OR the spirit could end up being a demon-like entity that calls itself "Havoc". Eh. It's your choice.
