An Aeon pocket watch made in Geneva, Switzerland, in 1852. Generations of the Fogs have relied on it to confirm the time despite not being able to see through the fog. He would adjust the time on it weekly to ensure the time at which he got off work was always accurate.

A top hat worn by the last Fogwalker, highly waterproof.
At some point, it became the symbol of the Fogwalkers. Oliver Fog inherited this hat after his father died. Given his age, however, it might be a bit too tall for him.

An umbrella wand custom-made at J&S Umbrella Workshop, London, by the last Fogwalker, and a highly efficient conductor of arcanum energy. The handle and the body are made of the same piece of ebony, which makes it hard and durable. On the body is carved "For My Son Oliver": it was supposed to be a present for Oliver on his 18th birthday, but unfortunately he got it as an inheritance.
