Along with all the other new additions to Wrath of the Lich King, a new type of item was added too: Heirlooms. These items are bind to ACCOUNT and can be transferred only to other characters in your own account. This is an interesting idea to say the least. None of the heirlooms are drops but must be found by receiving rewards in Wrath of the Lich Kings content. This content is usually taken advantage of by veteran players already around 80.
If you participate in Wotlk Content you will find the heirlooms designated to help in PVE or PVP.
Emblems of Heroism are designated more for PvE and can be found by beating heroic bosses or completing 10 or 25 man raids. Before rushing to buy heirlooms with the emblems make sure you take a look at the other items you can buy with them for your main, The heirlooms are good for alts leveling up, but if you want to focus on gearing up your main, make sure you check out the epic gear you can buy with you emblems of heroism.
