I'm sure this issue has been posted several times but the answers I've found don't seem to help so I'll be redundant for the sake of getting some help. I currently have access to Valor Mountain but no way to progress. I have no clue where this 'emotion powder guy' is located and I've nobody to interact with within the mountain. 1. I chose to keep the Magma Stone 2. I talked to the elder after the grunt disintegrated 3. I had the event w/ Venam and Melia, but couldn't find Venam in the building (or anywhere in general) This seems to happen more often with people that chose to keep the stone, which is unfortunate considering I thought the story wouldn't have changed that much. Hopefully I'm not soft-locked.
