Campaign Codex adds several new journal sheet types to Foundry and enables interlinking connections between them, items, actors and standard Journals.
The six main sheets are:
Groups
Regions
Locations
Entries
NPCs
Tags

Features
The basic sheet layout is shared between all Campaign Codex sheets; however, the Group sheet has some additional functionality and will be covered separately from the core five.
Each sheet contains a sidebar and a content panel to the right. The sidebar includes core information and menu links to change the content of the content panel. Some drag-and-drop linking is specific to the content selected with the menu link.
