Today I put forward an unusual set made up of a helm, top, bottoms and a cloak, dubbed Padomenes' robes. This is actually based on one of many content proposals that were made by the OSRS team for the now shelved Warding skill.
If memory doesn't fail me, the short of it is that Padomenes' robes were to be low-level, Prayer-centric robes that you'd learn to craft from the monks at the Edgeville Monastery. There was a tidbit of lore stating Padomenes to be one of Saradomin's generals, which coupled with the monks guarding the secret to his gear led me to picture the set as having a war monk vibe to it.
