Fadnare lies on the ground on the camp where Orrel spawns. He is for Babeliyna's quests from the NPC camp by the zone-in.
The first quest is The Lost Husband - Babeliyna asks you to find her missing husband Fadnare. She advises you to go eavesdrop on the conversation of Tissidrelle Windracer (standing next to her for a moment will complete this stage of the quest, you can even stay invis). Once you get the update from Tissidrelle then go to Fadnare and hail (you will have to drop invis, we did this by having our SK train the nearby mobs away), and return to Babeliyna. Quest rewards faction and experience.
The second quest is The Daring Rescue - return to Fadnare and hail again, 4 wereorc ambushers will spawn, you must kill them all and return to Babeliyna for completion. The ambushers can be single-pulled easily by FD or bard fade and kited, they run at 10%. Completion of The Daring Rescue also rewards faction and experience; this quest is repeatable.
Completed both quests quickly and easily with 72 SK, 72 ranger, and 75 ranger, FD pulling and kiting the ambushers. Sorry I don't remember more details offhand, was a couple nights ago.
