NPC's with no last names

I'm creating characters in an online MMA sim game and I've been using a baldurs gate theme for most of them. .Some NPCs have beautiful names, first and last... others have no last names at all.

The full namers

Ajantis Ilvastarr
Valygar Corthala
Yeslick Orothiar
Skie Silvershield
Edwin Odesseiron (God damn what an amazing name)
Eldoth Kron
Viconia DeVir
Keldorn Firecam
Mazzy Fentan
Nalia de'Arnise
Anomen Delryn
Jan Jansen
Korgan Bloodaxe
Sarevok Anchev
Shar-Teel Dosan

Then we have all the one namers

Alora
Aerie
Cernd
Coran
Dynaheir
Imoen
Khalid
Kivan
Minsc
Branwen
Faldorn
Garrick
Jaheira
Quayle
Safana
Xan
Montaron
Yoshimo
Haer'Dalis
Tiax
Xzar


So to make a purpose of this thread.... what last names would you bestow upon the NPCs without last names? I'm going to come up with some of my own and post them again in this thread in a little while :)
