Second Breech

The third major holiday of the Dwarf calendar, Second Breech (33rd Day of Brauzeit) is the time when the family beer kegs are opened and tested once again. As before, songs and tales of Ancestors and heroic battle are the norm during this time. Few Humans celebrate Second Breech, unless they happen to belong to families of brewers or distillers.
