Hunters:<br/>I'm assuming Rennell keeps the letter private, so the contents of the letter are currently only visible to Rennell, unless he decides to share them, or others make an efford to peek.<br/><br/>Rennell knows which temple is mentioned. Gaven and Zulsaran could, based on their players' decision, as it's fairly common knowledge. Of course, wait until you've contacted Muse before actually leaving the tavern.
