O, Unknown! is a mysterious fragrance from Imaginary Authors released in 2017. Created by Josh Meyer, this perfume combines the sophistication of tea with powdery orris butter and woody undertones. It's a complex composition that balances between classic and modern sensibilities.

Opens with a distinctive blend of black tea and smoky Lapsang Souchong, complemented by rich orris butter that creates a powdery, almost shortbread-like accord. The heart reveals earthy Kyoto moss and creamy sandalwood, while a subtle musk adds depth to the base. The overall impression is of dusty books, warm tea, and sophisticated powder notes.
