The Lastlight Chronicles
'The Forge' is a semi-secret alliance of adventurers that fear civilisation is unprepared for the return of great evil. To prevent destruction of the lands, they scour the lands for ancient artefacts that they can use against any potential oncoming threats.
The PCs may have had heard rumour of the Forge, but the first named member they know of is Gundren Hearthhold. Another agent of the Forge is said to have retired to Vandalin.
