Maybe it's a name impanted in your mind? Otherwise it's a pretty common trope to have your name be the only thing you remember. But besides that, why would you call yourself The Dark Urge either? I think recalling or otherwise having a name is the less strange of the two options. I imagine that we actually will be able to change our name, it's just that they didn't bother to do it this time around for the PFH and that was the default name.
