Durandal
What it does
PowerPyx lists it as a legendary sword reward. GameSpot's northern map also pins the name next to St. Mihai and Erkas.
How to get it
Reward for The Cursed Chasm. IGN also notes a silver cache at the bottom of that chasm.
Not a random world pin. Open the quest, finish it, take the sword.
