What was the origin of Ravel?
We had a number of physically powerful enemies in Torment, and I thought a night hag would be a good adversary, especially if she was a cryptic, deadly puzzle maker. As the game went on, the idea that Ravel was a branching creature whose life resembled a great tree (or bramble) stretching across the planes, was in love with the player and she genuinely tried to help people at times (only to have it turn against her and the recipient) seemed to be some good hooks to make an adversary.
Writing Ravel was perhaps one of the experiences Iím most proud of in my career. I felt like she came together nicely, and she had a really distinctive tone.
