On the night of Breves Dies 12000 the mages of Novopan created the largest fire ever seen in the world. So large they hoped it would cast enough light for anyone on Lunopan to see it. Two whole Annum they waited, creating this fire each Breves Dies. On the night of Breves Dies 12002 a light appeared on Lunopan that had never been seen before. The Mages took this as an acknowledgement from Lunopan that they had seen the light from Novopan. Over 400 Annum have passed since that day with each Breve Dies passing with no more lights from Lunopan.
Eve of Ceteri is the annual celebration of the reply from Lunopan. The first of which was in 12002.
