APD is the measurement of time and the opposite of BPD. It informes the details of the events taking place after Purple-eye's disapearance.
History[]
APD first appeared in Dust and Shadow, although not directly mentioned. Before the events caused in the first novel, time was never measured, and the Races of Amsnorth only told time through the cycles of moons and suns: years and days.
APD and BPD are both the main reasons of time of past, future or present. They were both founded in the first novel, and will be used as the main timeline within all the novels and expanded stories.
APD:
A: After
P: Purple-eye's
D: Disappearance
