Lore & Dialog
Sir Rylanan tells you, "I've recently been assigned to Holtburg to build a garrision and be on the lookout for suspicious happenings. There is one fellow on the outskirts of town that I've been keeping my eye on. He's just moved here from Marae Lassel and sometimes comes into town for provisions. He says he's been "reformed", but I can spot a bandit when I see one! Townsfolk say they've spotted shady-looking guests coming and going from his house at odd hours. Could you go check on him? His house lies to the northwest of town, past the Holtburg West Training Academy."
