We get to learn more about the Kalendarium. Given the existence of the awakened and the earlier imagery of the 13 constellations with the MC, these 'Gods' can more or less be confirmed as actually existing in some form. Now I'm wondering what their relation to the apocalypse is.
Kalendarium means almanac or Calendar, and stems from the latin calendarium, where it refers to a book of debts. One does wonder why there are 13 instead of 12, perhaps it somehow relates to the apocalypse?
