BioWare has announced new DLC for Dragon Age: Origins, and it's called Leliana's Song.
In it, you assume the role of Leliana, a bard involved with a criminal organization that "deals in political secrets".
While on a high-risk mission with her mentor Marjolaine, she becomes "entangled in a game of intrigue that she cannot escape with just her beauty, charm, or stealth".
She must kill or be killed, apparently.
When you complete this campaign, you will unlock a unique reward that transfers into your Awakening and Origins campaign.
It'll run you $7 - date yet to be determined. No word on if she sings again this time around or not.
