World of Shadows

Sky Commander Adaris was seriously injured during a Skettis incursion. He's been in and out of consciousness since.$B$BI fear he has succumbed to a feverish delirium. During brief lucid moments he demands that I prepare an elixir made from shadow dust carried by the arakkoa. He seems to believe it will allow him to see into a "world of shadows" where the arakkoa's true leaders dwell.$B$BI do not believe this nonsense for a second, but I fear he won't rest until I obtain such an elixir. Will you help?
