There are several different characters, so any description would work. The ones I am trying to create are mostly minor characters, the ones that are just there to fill an empty slot. The readers would hear the name a couple times in stories, or meet them at a party; something like that. It requires a name, but no real personality or background.
The few semi-major characters I am still trying to name are similar. Their descriptions are not set in stone.
For me, I usually find a name I can use, and then build on that. And since I am having difficulty finding names, everything else has become more difficult as well...
