British WWI Soldier's Helmet from the Battle of the Somme River

Origin
On July 1st, 1916, the British implemented their famed European Slow March, a plan to approach the onfacing German army not in a typical frenzied dash across no-man's land, but in a 'slow and steady' march that was intended to make it harder to be hit and to inspire intimidation. However, the idea fell apart when put in practice, resulting in the death of nearly 20,000 British soldiers.

Effects
The helmet absorbed that terror, and the feelings it radiates are so cold, so saddening, and so scary that it has been given a permanent place in a tank of neutralizing fluid. Warehouse Associate Leena *CLASSIFIED* is known to tear up whenever the artifact is brought up.
