His story reveals the value that Christians placed upon the bodies of the faithful in the ancient world. After his execution, the body of St. Isidore was shoved into a cistern and placed under guard. St. Myrope, a young Christian woman (celebrated on December 2), was willing to be tortured and killed in order to recover the body of St. Isidore.
The name Isidore in Greek means straight spear and reveals a bit about the saint and his occupation. The Orthodox Church celebrates a number of military saints and St. Isidore is one of them. He was an officer in the navy.
In my current campaign, all adventuring clerics are deacons, one of the three orders of ordination in the Church. This ordination happens prior to their adventuring career; however, recently I've been having second thoughts on this. Labyrinth Lord and 1ed + give clerics spells at first level. Despite the fact that the players in my current group would complain, I am coming around to prefer the OD&D and B/X version of cleric which does not get a spell until 2nd level. This transforms the cleric's first level of experience into a right of passage, where they prove themselves. This vision allows room for ordination to the adventuring deaconate to be delayed until clerics are due to be able to cast 3rd level.
This is all a round-about way of re-casting the military saint. I wouldn't blame anybody for seeing St. Isidore as a fighter or a even paladin; however, I would challenge this view and argue that the military saint is actually a cleric. Being a soldier explains the fighting ability and the proficiency with armor. Note that St. Isidore brings Christianity to the people of Chios — very cleric-like behavior. Finally, the OD&D and B/X vision of the cleric, with no spells at first level, leaves room for saints like Isidore to be seen as low-level, non-ordained clerics.
The Anchor of St. Sulita
This device appears to be a smooth stone weighing about 100 lbs., with two holes carved in it. It will radiate strongly of magic if detected for. Its efficacy will be revealed when a rope is threaded through the holes and it is used as an anchor. If the person throwing the anchor into the sea pictures a destination within one day's travel, the anchor will unerringly pull the ship to that destination; however, the path taken will always be a straight line. Therefore, any obstacles will affect the boat accordingly (it will be pulled ashore on an island, be torn apart by rocks, sunk by holes being torn in the bottom by coral reefs, etc.). The Anchor may be used in this way once per day.
