Celtic Heroes

So I had a level 3 storage character like a year ago I transferred all the stuff to my main and I forgot my storage account, there's nothing on it but I want to delete it so I can use the name. Anyone have tips?

If you attached an email account to it, you can claim it using that.

Otherwise come up with something else. This game is not like others, and there is name options you would think were taken but aren't.
