Runewell were powerful magical artifacts created by the ancient Runelords of the Iskari Empire.

Seven types of runewells were created; each was attuned by its creator to one of the seven schools of "Sin-Magic;" greed, sloth, wrath, envy, lust, gluttony, and pride.

Runewells were designed to extract magical power from the souls of mortals attuned to one of the mortal sins and store them within, and could be used to create horrific creatures known as "Sinspawn."
