Dream essence is an alchemical creation developed by Aubrey to revisit the conversation she saw between Samot and Samothes. A silvery, mercury-like liquid, it is a distillation of a lucid dream, perfectly recreated for the user.
Delivered orally or by injection, dream essence induces a trance lasting a couple hours, with the length depending on the amount taken. Users remain in a dazed state after emerging from the trance. It can be made from materials easily found in Marielda, including chips of obsidian.
The substance has been kept out of common usage by the risk of dependency, as people may use it to recreate memories of loved ones and end up losing grasp of reality.
