Hero Inventory

The bottom half of the Inventory panel shows your inventory items; your character and all your Heroes share that same inventory. The top half of the Inventory panel includes an inventory interface (a "paper doll") showing your character or a Hero, along with the weapon, armor, and shield or focus item that character or Hero is carrying.

A menu at the top of the Inventory panel can change the character or Hero shown on that inventory interface. After you've selected your character or a Hero, you can move a weapon, shield, or focus item from your shared inventory to that character or Hero (or move them back). http://www.guildwars.com/gameplay/gwnfeatures/heros1.php
