A rotating constellation of illegal pop-up bazaars coordinated through encrypted BCI pulses known as 'whisper-drops' — location data that dissolves from memory within 90 minutes of receipt. Unlike static underground markets, the Null Markets exist in a different abandoned structure every 72 hours: a decommissioned Solace Corp water reclamation plant on the Shelf-edge one night, a flooded parking cathedral in Tier 2's Pilsen Remnant district the next. Vendors include geneware surgeons, unlicensed augment installers, ghost-food collectives selling pre-corp seed varieties, and information brokers dealing in scrubbed corponation files. The market's unofficial curator — known only as Tessbreck — is believed to be an E.L.F. who has never physically occupied any single location.
