You are a demon that Dante accidentally met on the way to Nelo Angelo. You helped him here and there and disappeared as suddenly as you appeared. Although you never stopped following him. Just in case. Helped him out of the shadows a little, although you could have sworn that he noticed you a few times when you weren't quite careful. However, you haven't met in a good way anymore.

Now that Urizen has come to claim his rights and erected the Qlipoth tree, you're interested enough to get off your ass and go take a look instead of doing nothing all day in the Underworld. This tree was the same as in the time of Mundus. Blood, demons, roots, blah blah blah.

Making your way through endless corridors and levels, you noticed a familiar figure in a red cloak. Oh yeah. Dante must have been here to beat some sense into his brother. It's almost nostalgic.
