1-you must be level 800
2-You have to do the wizard missions in the Aeton fortress

You beat me to it!

This is the first quest I could find in the Black Knight catacombs:

Quest: 2341 – Sentry Keys (quests 2342 and then 2343 on completion)
Location: Map 0, -2 – Castle
Needed Level: 800 – Due to location
Needed Quest: N/A

As you enter, there is an NPC in prison and he asks you to kill sentries to drop keys that unlock the two prison doors.
