An Axe

You decide that next time some monster or cruel marauder tries to fuck with you, you want to be able to chop their head off. Hence, an axe.

Glaw nods with approval and lends you the gold for the axe. He purchases a breastplate. Dai buys a shortbow and arrows, and Murdoc buys a spear.

As you are purchasing your new equipment, the blacksmith asks, "Planning on delving into the Sunken Tower, I bet?"

"What's the Sunken Tower?" you respond.

"Oh you don't know? Most folks who come in here looking for weapons and armor are gettin' ready to plunder the Tower. It's just an old story that says there was once a Lord who crossed some powerful devil and was cursed so that his keep sunk into the earth, and he and all of his knights were turned into terrible monsters. Legend says the king's ransom he stole from the devil is still down there in that tower under the earth. People argue about where the tower really is though."

With that, she takes your gold and hands over your weapons and armor.
