Lot's Salt in Lore
Lot was forewarned by angels of the destruction of Sodom and Gomorrah. As he and his family left Sodom, his wife looked back despite the angels telling them not to, and she was turned into a pillar of salt.
This story, including why Sodom and Gomorrah were destroyed, can be found in the Bible: Genesis 19:1-26. The section where Lot's wife looks back is in Gen 19:24-26.
- This Heavenly weapon was referred to (thus named) as the "Salt Crystal" in the Official Supernatural Magazine (Issue #22).
