The shattered History of Island Inquest
The shattered History is a catch-all name for history at large in Inquest.
Throughout time and by Magic history was (quite literally) changed, often by aa single person's whim. Most of the past is no longer linear or was lost entirely.
There are no sources that provide definitive truth, as there are many examples of historic events that only survived in either oral traditions or written records that actively contradict each other.
