The Legend of Stalvan

I'm here because I received a letter from my brother Stalvan, who I haven't seen in years. On arriving here, I was told he was dead... The entire town refuses to offer any further explanation. Any mention of his name is met with terror and suspicion. As if I didn't have enough of that myself! I'm afraid of what will happen if my frustration and anger grows any further. I beg you, help me get to the bottom of this. Implore Clerk Daltry for any information he may have on my brother.
