The importance of religion in Medieval society cannot be understated. Religion, or more importantly, the eternal consequences of not following it, were so deeply ingrained that wealthy people sometimes sought to use their earthly possessions to help ensure a more comfortable eternity after their deaths. To this end, many wealthy nobles and kings devoted some of their assets to the creation of a chantry, or fund dedicated to the saying of Mass for a specific purpose, with the purpose often being for the repose of the soul of the person establishing the chantry.
At minimum, the chantry fund had to include a stipend for the support of a chantry priest, who was responsible for saying the Mass on specific days or times for the stated purpose. Many such Masses were said at chantry altars erected within existing churches. Wealthier patrons paid for elaborate “upgrades” for their chantry altars, such as golden implements or costly vestments. The wealthiest paid for additions to be built on existing churches; a historical example of this is the order given by the English King Henry V to construct a chantry chapel over his tomb in Westminster Abbey.
While the number of occasions a chantry priest may be able to assist D&D heroes is predictably small, the existence of a chantry can provide useful information to a party of heroes, particularly if the chantry was built by or for a villain. What evil did the beneficiary of the chantry commit to warrant a chantry’s construction and maintenance?
