Sister Garaele — The Fallen Acolyte
Sister Garaele arrived in Phandalin eighteen months ago, dispatched by the Harpers to investigate rumors of a spellforge hidden beneath Wave Echo Cave. Her superiors in Silverymoon chose her precisely because she is forgettable — plain-featured, soft-spoken, the sort of elf who vanishes in a crowd.
What the Harpers don't know is that Garaele's faith in Tymora has been crumbling since the night she watched bandits murder a caravan of refugees while she hid in a ditch, paralyzed with fear. She still wears the goddess's silver coin around her neck, but she hasn't felt its warmth in months.
Secret: Garaele has already located a partial map to Wave Echo Cave — she found it sewn into the lining of a dead miner's coat at Barthens's Provisions. She hasn't reported this to the Harpers because she is planning to reach the Forge of Spells herself. If she can channel even a fraction of its power, she believes she can enchant her holy symbol strongly enough to feel Tymora's presence again — to manufacture the faith she has lost.
At the table: Garaele will eagerly help the party, offering healing and information. But if they mention Wave Echo Cave, her body language shifts — she becomes evasive, fidgets with her coin pendant, and changes the subject. A DC 14 Insight check reveals she's hiding something. If pressed, she offers to join the party as a guide, but her true goal is reaching the Forge before anyone else.
