This is where question or answers about the Cult of Bloodmoon go. CoB doesnt have gods or anything besides eating of the Bloodmoon fruit. Basically the temples are built to control consumption of the fruit. Eating of the fruit causes visions/predictions or anything the player wants to explore in a roleplay context.
A brief history of Bloodmoon fruit (picture a dragon fruit that grows on palm trees instead). Bloodmoon fruit is from the tomb island regions originally growing mid-Dwilight the best. Used by the Dwillii people for thousands of years in shamanic rituals etc. Glaumring is born in Port Raviel, immigrates to north Dwilight bringing with him the first seeds, plants first seeds in Storms keep, the plants change in the extreme north creating a harsher smaller plant. Glaumring moves to Asylon. The Saxons wage the first war on the plant destroying almost every plant in Thulsoma. Glaumring uses the Thulsoma plants and crossbreeds with native plants in Vakreno heaps in the COB original guildhouse. The guildhouse falls, plants grow wild in Vakreno. The new strain in the most powerful ever.
-Gift of Bloodmoon from Thulsoma sent by Glaumring to the Prophet of Sanguis Astroism.
Lady Ven Dhalgren discovers the plant while tending her new estate in Vakreno. Begins to tend them asks Glaumring for guidance.
-first gift of Bloodmoon to the Zuma, it pleases them.
Glaumring unleashes Bloodmoon on Asylon entire, a huge festival orgy that goes on for days happens, the kingdom goes mad.
Nobles protest, some indulge, the realm is split between the advocators of Bloodmoon and its destroyers.
In order to establish order, the first temple to the Cult of Bloodmoon fruit is built in Vakreno in order to train people in its proper use.
