the dev really put up a lot effort for this vaivora set, especially the description. There is some chronological story if you read them all. Some of the interesting ones were:
pike: the first vaivora
2h sword: 4th wall breaking
rod: we got the fake product
rapier: becoming one of the most expensive vaivora weapon in ktos, matching its description
shield: tragic story behind it
bow: last part of the story
