I have run many, many public events and opened chest after chest, but nothing is dropping Insight which is required to reveal this Opaque Card and continue "The Bladed Path" parent questline. I opened a new topic because the existing one had typos which could be confusing to others facing the same issue. Is this a time-gated card? Nothing on the card specifies a location or type of public event to complete, and I have tried to acquire Insight on several destinations including the Throne World & EDZ.
