Loyalty Day is a holiday in the nation of Cheliax commemorating the date on Calistril 19, 4640 AR when House Thrune signed the Treaty of Egorian, declaring it the victor in the Chelish Civil War and ruler of the empire. Because of House Thrune's well-known ties to the infernal, this holiday is also observed by the Church of Asmodeus who consider it a feast day. The church along with local governments provide a free meal to all citizens to remind them of the benefits House Thrune provides them with.
