Vitrea

Vitrea is a Sulfur Imp who lives in Lumen City.

In-Game
Chapter 4 Vitrea is encountered in the Grand Ziggurat prisons. After investigating the cell that held Sia, Soriel will ask Vitrea if she saw what happened to Sia.

Vitrea says she saw some High-Ranking Imps, she also mentions a special kind of fire magic which was able to hurt Sia despite her ethereal form, and does recall a hooded figure occasionally accompanying the Nobles when they took prisoners out for interrogation.

If asked about her home, Vitrea will go on about the enmity between the Obsidian and Sulfur Imp clades and how their relationship has deteriorated lately.

When asked about the Warden Vitrea will mention how she saw Soriel being dragged past her cell. After being prompted to tell them more about the Warden, Vitrea will go on about how the Warden is well known in Lumen City, and how she's known for always being loud and yelling.
