Well, a few start with me picking a letter or looking outside. But i kinda stick em in a few personal methods.
Like if its an avian of sorts, i may use a name such ad Qualia or Hoskei
If a reptile, Mileen,Zharran, or Hryssar
If dragon, Haid'ku, Zeth'tir,Hryssar, or depends on element for name.
As you can tell, i play scale or feathers a lot
