IGN has conjured up a brief overview of the Broodmother, the tentacled Hutt-like creature we've seen from time to time during the many Dragon Age: Origins trailers. Here's one of two paragraphs that accompany the 45-second video:
Today, we bring you the first details of the Broodmother, a nightmarish creature spoken of in hushed, terrified whispers in the subterranean halls of the Dwarves. Continually battling with the underground dwelling Darkspawn, the dwarves have sacrificed much of their empire to the hordes of beasts. Every now and then, knowing that the source of Darkspawn corruption lies outside the doors of the Dwarves, parties of Grey Wardens venture deep into ancient abandoned Dwarven tunnels, trying to crush their enemy on their own territory. The few that were lucky to return to safety seemed mentally broken by the experience, feverishly mentioning tales about a disturbing beast known only as a Broodmother. What the Broodmother is, and what it is doing underground is a complete mystery. However, one thing does stand out across all these stories - its insatiable hunt and hunger for Grey Warden flesh.
