I have a GW1 account as well as a GW2 account. Am I able to merge them into one account?
The GW2 Support webpage offers solutions to a great deal of problems and questions. Jayvux, you can choose to link your Guild Wars 2 purchase to your original Guild Wars account during Guild Wars 2 registration and you can also choose to link your original Guild Wars account to your Guild Wars 2 account after registration.
For more details on how to proceed with both, check the following webpage.
Have fun in Tyria!
