This is a notification that "Tyrion" of Imperial has had his name updated to "Tyrion d'Fidelis".
This goes as per the following rule on the website:
"If however you wish a surname to be added or changed, you may contact staff about it, but it needs to backed up with enough roleplay (story on forums or screenshots from game which are posted on forums)."
If anyone is ever looking to have a last name added, we encourage you to contact the GMs and we can provide you with guidance about what is expected. Please note that it will typically be a multi-month undertaking before we will consider adding a last name, and even then it is not guaranteed.
First name changes are still impossible, and removing/changing a last name will be particularly difficult (excluding divorce).
