Soil Stradivarius

The Soil (Pronounced 'Swal') Stradivarius was one of the most prized and rarified instruments ever made by the legendary Antonio Stradivari, and after the events of the nuclear war, may be the only Stradivarius left in existence, and indeed, could be thought of as utterly priceless, as the knowledge and technology to craft such instruments has long since died.

The only reason for the Soil's survival was due to it falling into the hands of a talented, yet naive young violinist, Hilda, who was selected to enter Vault 92 as part of Vault-Tec's desire to 'preserve muical talent'. However, after the experiment conducted in the Vault went awry, the Soil was locked away in its own perfectly crafted case, designed to maintain the right humidity and tempterature to keep the violin in optimum condition.

Agatha is, essentially the rightful heir of the Soil Stradivarius, given that she is directly descended from Hilda, although the instrument can be sold on to other merchants for a small sum.
