The White Dragon

The threat hanging over the whole region. The party has never laid eyes on it — but everyone else seems to know it’s coming:

• The Quest Master’s dragon rumors sent the party to warn Gnomengarde (Session 1).
• Dax’s orc rumors said the same thing (Session 2).
• Harbin’s Dwarven Excavation contract exists to warn the prospectors that a white dragon has moved into the area (Session 4).
• Guildmaster Thornton pays standing coin for any dragon intelligence (Session 4).

Sooner or later, the warnings run out and the dragon shows up.
