I am old school when it comes to gaming. Last names wouldn't be required for the staff to keep track of accounts and players, it would just be a tool for us to easily identify others. So then, give us the same access by another method. I would enjoy having to cast a spell of identification in which you could observe linked characters on that player's SotA account. Cast the spell directly on a player in line of sight, on an object dropped by a player(last player to touch it), or if you know their name then cast and find a creative way to cast the spell on a name.
