Maric's Blade

King Maric's Blade can be found in a locked chest along with Cailan's documents in Return to Ostagar. It is a leveled item.

As this is a dragonbone blade, it may be the same sword Maric found in the Deep Roads during the events of Dragon Age: The Stolen Throne. It clearly resembles the blade Maric is wielding on the cover, though this sword's runes glow yellow instead of blue.
