Shale

Shale was a supposed companion who was cut from the game. The Player Character would have had the chance in helping Shale becoming a "real person" or a mindless killing machine.

Background
Shale is one of the last Dwarven war golems. The knowledge to create such golems was presumably lost after the invasion of the darkspawn and the sealing of the Deep Roads.

Trivia

 * It has been confirmed Shale will only be available to the character in the Collector's Edition of Dragon Age:Origins.&#160; http://www.gamestop.com/Catalog/ProductDetails.aspx?product_id=75494
