Zenumist and the missing Alchemist

I'm quite stumpred. It says to check his house for clues.. I've found the pipes, the wall, the desk.. and it says something about a pendant. Any insight?

There's no "You have completed _____" text like in prev quests. I just looked at my quest log and it had the symbol for complete. I think you talked to the right things, just make sure pendant one for sure and talk to the person who gave you that quest [Carson/Zenumist leader or Phyllia]

Talk to the Picture frame, and the wall right above the candle (I know it just says candle there, but it's slightly higher than the candle for some reason.)

Awesome, definitely just bookmarked that page. Now to finish the quests..
