Death Knight Quests

First an overview of the Death Knight Hero Class Per WoWWiki.com

The death knight is the first hero class in World of Warcraft. This is a separate character from other characters and can be created as soon as one of your existing characters on any given server reaches level 55. After making a death knight, you will not lose access to any of your existing characters. The death knight will start at level 55 in Acherus: The Ebon Hold over the Eastern Plaguelands, with multiple spells and abilities ready to use, and a set of uncommon gear. When you leave Ebon Hold, you will have a full set of rare gear ready for Outland. Through the Death-Knight-specific quests in this necropolis and the surrounding areas, the character learns to master the power of the death knight and learns to use this new power for the will of the Lich King. Quests will take them outside the necropolis and into an area within the Scarlet Enclave.

Players can create one death knight per realm, the player must have a Wrath of the Lich King account and a character of at least level 55 on their account in order to create a death knight. There are no racial limitations for creating your death knight, but PvP servers are still limited by faction (i.e., if you have an Alliance character on a PvP server, you cannot make a Horde death knight on that PvP server).
