No worries
I to like me some good ol´ dark elf ladies from time to time
Anyway - guys ! Log into the game ! We got Nazuna back ! WE GOT NAZUNA BACK !!!
*As in - She is preselected as your assisstant on your main screen so enjoy her properly while you can !
I think this will last only for the remainder of this event (the lifestream) after which she will be gone once again, since normally you cant have her be your assistant.
