Harlan is a guard in the Town of Dion on the right side of the village when heading towards the Einhasad Temple.
"Greetings. I sincerely welcome you to our village. There are many dangerous area around here, so you must be particularly careful when you travel. Be especially careful from that point past the temple in front of me, where you can see the ruins left by the giants of ere. You never know when or where some monsters will make a surprise attack on you.
(ask about the giants of ere)
"You want to know about the giants of ere? I'm sorry, but I don't know much about them myself. All i know is that they lived in these lands a long time ago and that their knowledge was far greater than ours.
Now that I think about it, perhaps the Elves know, since they've been around longer than the Humans"
