John Duns (commonly called John Duns Scotus) was a 13th-century Catholic philosopher and theologian. At some point he was made Immortal by an unnamed elder.
Immortality: John Duns gained Immortality from his Elder master, and therefore does not age (though he is vulnerable to injury and poison). Unless his master chooses to take his immortality away, John Duns may live for thousands or millions of years.
- Duns Scotus was looked upon very poorly by philosophers in the decades and centuries following. Those who followed his teachings were titled "Dunse" by the thinkers of the time, which is where the English word "dunce" (meaning "fool" or "idiot") originates.
