- I can no longer use the Black Market Auction House after the Shadowlands Prepatch on my alts.
- Provisioner Drako is not offering "The Night Market" quest.
With the prepatch for Shadowlands, the requirements for the Black Market Auction House changed. Only max level characters are able to use the auction house. You can find this change in these patch notes.
In order to access the Black Market Auction House post-Shadowlands release your character needs to talk to Provisioner Drako in order to pick up a quest "The Night Market" and start a short questline which will then let you conduct business with Ta'xera.
