Hello Nelly and welcome back to the community ArgonathRPG.
There might be a small chance to retrive your account, after 6 months of inactivity of the account it will automatically or put by an owner into a folder for inactive accounts.
They do this so old accounts won't slow down the server.
I would say this is up to Aragorn or Gandalf since they're the owners and they have access to this kind of things.
You could easily try to PM Aragorn or Gandalf on the forum nicely and ask them about the matter.
Their forum names are Aragorn/Gandalf.
