Saga

Held on the 33rd of Vorgeheim, Saga is an important and grim holiday of the Dwarves. Songs of the trials and epic battles of troll slayers, longbeards, and iron breakers fill the Halls of the Dwarfs. The Ancestors are revered during this holiday as their exploits are told over numerous tankards of ale. Humans, particularly those who live in areas with large Dwarf populations or near the World's Edge Mountains, often take up this celebration as well.1a
