Originally, the character Shale was meant to be the size of the other golems in the game. However, the developers had trouble with her fitting through doors and originally cut the character entirely. Thanks to a delay in the release schedule, they had some extra time and decided to create a new, smaller character model for Shale. This is referenced in the game, as she said she was "chiselled down" by her previous owner.

At one point in the game, The Warden can obtain a long sword named "Oathkeeper". The sword is described as a blessed blade commissioned by The Chantry and given to Templars as a reward for their deeds. It has been speculated that the sword is an homage to George R.R. Martin's book series "A Song of Ice and Fire", as the sword shares the same name as the sword given to Jaime Lannister by his father Tywin, which Jaime later passes to Brienne of Tarth who then names the sword. It is known that the book series was an inspiration during game development.
