The ancient symbol looks like an eroded holy symbol without the string. Players cannot string this symbol with a ball of wool, and it has no use except as part of the miniquest.
Players should place it in display case 37 (ground1st floor[U.K. floor]). Its information reads: "This small symbol was used as a decoration on the Saradominist altars throughout the city. Two or three examples have been found, but this is the best. Worked in blue-enamelled iron, it has not survived the ages well. We believe this to be from the early years when the city was still being built."
Because it is a symbol to Saradomin, it is believed to be from the ruins of Saranthium as opposed to Senntisten, which was an earlier settlement on the same location and of Zarosian religion.
