Mid Year Celebration - 16th of Mid Year
Lore: Perhaps to alleviate the annual news of the Emperor's latest tax increase, the cities' temples offer blessings for only half the donation they usually suggest.

Harvest's End - 27th of Last Seed

Tales and Tallows - 3rd of Heartfire
Lore: A few of the oldest, more superstitious men and women do not speak all day long for fear that the evil spirits of the dead will enter their bodies.

Warriors Festival - 20th of Sun's Dusk

North Wind's Prayer - 15th of Evening Star
