Inside this wiki you can find and learn about almost everything in Arcadia that will be relevant to this campaign.
Please feel free to roam about and read up on anything and everything. Keep in mind that the information will exceed what your character actually knows. However, rumor and myth reach all corners of the world and such whispers can be accessed through gather information, knowledge checks, or even just being lucky and overhearing the right conversation. Concrete information on Gods, Races, Kingdoms, etc will often require knowledge checks, though much can be considered common knowledge. These all can also be remembered if I believe your character could have ever reasonably run across it.
You can find information on Legends and Lore, legendary, or powerful figures. Names of and some information on NPCs important to the campaign can also be found in the Characters tab. New information on important NPCs, items, and locations will become available as the campaign progresses.
