I tend to just choose names that sound nice and not really worry about meaning. If it has a cool meaning and sounds nice, bonus for me. But I actually planned out names for my next playthrough, but whether they have meaning for the character or not--
Origins:
Yura Mahariel - Yura is just one of my favorite Korean names and the first name to come to me during customization uwu
Maira Cousland - My future Warden, I wanted an 'M' name and Maira sounded pretty. It means Myrrh apparently, hah
And I named Dog Cerberus because I'm so original :')
DA2:
Reina Hawke - Again, just another name I really am fond of and I name a lot of my characters Reina.
Hazel Hawke - With the appearance I'm planning Hazel just sounds nice
Inquisition:
Artemis Lavellan - My inner Greek Mythology nerd was coming out and I just went with it
Robyn Trevelyan - It was Robin before but I'll spell it with a 'y' because she's special. Also I wanted a gender neutral name.
