Tomorrow is the finale of a two and a half year #DnD campaign. They will have delved dungeons, discovering the pre-legend past when the continent was shared by all.
They will have slayed dragons, five of them!
They will have spread knowledge and magic to the common people -- who know use cantrips to live better lives.
They will have lost friends and companions. 

 Maybe they'll even survive the Armies of Darkness. The final dragon they are fighting has an army of enchanted beasts with spells and the dragon's name in the common tongue is Darkness.
