Silvia H. Raven

Silvia H. Raven is a mysterious character that plays an unknown part in the lore and the ARG.

Biography
Her surname can connect her to Raven Research Institute, possibly as a founder or director. Raven's portrait is seen next to Mikhail Rosenthal's in the Metal Worker's Union building in metro, implying some connection to Rosenthal or the union.

Raven is also the author of the book "The Tunnel of Water Trees", a book seen throughout the game several times. The book's title is also cryptically written on a faded mural in a cavern in Hammer Valley. Furthermore, the cover of her book has a photograph of someone in a diving suit. The only other occasion a diving suit is seen is during the interrogation in city gates.

Trivia

 * Although it could be coincidence, Raven's portrait has a marking that goes across her neck. The implications of this and to "The Headless Raven" are only speculative.


 * Previously it was only theorized that the portrait in the MWU building was of her. It was confirmed on the 16th of July 2021 when an animated avatar for Silvia was added to the Steam Points Shop depicting her portrait with a glitchy animation. By saving the animated avatar as a GIF File and chopping it up into separate frames, one of the frames can be seen to depict the Mörkö mask overlaid over Silvia's face.
