If by this you mean the dracolich pet, you must first buy a baby red dragon pet from Aria's pet shop or Galanoth's dragonslayer shop and then you must /join death. There you must accept the quest "turn a red baby dragon into a dracolich." When turned in, the pet will be given to you.
It is in the Evil Rep Shop located in Shadowfall (/join shadowfall). When you reach the map, go through the dragon (Fluffy) mouth and then the skeleton doorway on the left. There you will see a skeleton holding a spear and you will be able to buy it from the Evil Shop there if you're currently evil.
You have to link your Dragonfable Dragon Amulet account to your AQWorlds account.
You cant you have to die.
