Names from various Final Fantasy titles. Playable character names for workstations. Names of summons for servers. Names of cities and locations for networking devices. Names of Moogles for some services that I wanted to give a unique name.
I generally like to take a whole “universe” for naming schemes. Star Trek is another favoured one, since you get a variety of names in different categories. Characters, Ships, Places, etc.
+1 for kagi. I tried it out with their trial offer and liked it enough to stay with it. Used DDG before that.
