EXPEDITION CHRONOGRAIL
Handcrafted from the crushed remains of a long-extinct thought form. This lens allows its bearer to [remote control] time. Each viewing session is limited to 33 seconds, after which the object must be submerged in saltwater to recalibrate.
Chrono-fatigue may occur if used excessively. Symptoms include déjà vu, time dilation, and echoes of past selves. Users are advised to anchor themselves to a fixed memory before operation.
