Vigo is an unknown Character in Template:IconLink, who is only mentioned in descriptions and names of Items, luck-based and spawn-location altering Template:IconLink.
Examples being Template:IconLink and Template:IconLink along with several quotes from her on some of the Perks such as Template:IconLink.
Vigo is also credited in the quote for the Engineer's Toolbox, having apparently created the original tools which the ones that are found in the fog are supposedly a 'poor replica' of.
It is presumed that Vigo was a Witch or Shaman as his Offerings influence Survivors' luck and spawn locations, though the Engineer's toolbox having apparently been originally owned by Vigo might suggest otherwise.
Because of his mentioned ability to create things as well as bend the rules of the fog, it is possible that he was the creator of the Black Lock.
