Muck about and look for something interesting
Examine scrolls
examine the books

Disregarding any privacy of Lucas, you decide to rifle through his property.
On the shelf, there are a series of color coded scrolls. Each one seems to be a template for various kinds of weapons. It goes like this.
Red: Blades
Yellow: Shields
Blue: Pole Weapons
Dark Blue: Magic Staffs
Green: Archery
White: Armors
Gray: Blunts and Maces
Black: Great Swords and Axes
By the looks of it, there was one on the top shelf, next to the Black Scroll. There is a fine outline of dust where it was. It's not there anymore.
The Shelf contains a guide for crafting and assembling weapons and armors, A history book of all different kinds of weapons throughout history, a guide for ammunition such as arrows, bolts and throwing stars, and a guide on repairing armors and weapons.
The Second shelf contains a high quality Sword. There is a hole through the center of the guard. Probably for style. The blade is round, like a saber, half way up. The rest is sharpened like a regular sword.
