The Legendary Sandwich is a mystical sandwich made by an old sandwich wizard. The Titans reforged it, only for it to get eaten by Silkie. It first appeared in Legendary Sandwich.
According to the legend, in a long forgotten kingdom, a king asked a man to prepare a sandwich. The sandwich was stored in the king's tower for six days, and on the seventh, it was ready. The sandwich was delicous, and it would make the king immortal, making him rule his empire forever. The prince betrayed the king, and the king realized the sandwich was too powerful, so he hid all the ingredients, which are guarded by Sandwich Guardians.
