Need help with naming OCs for a new fic idea

So, many of those who have read my stories know me as a crossover writer. That's good, because that's most of what I write. In fact, I have another few crossovers in the works. It's what I do well: take games I enjoy, and throw ponies into the mix.

What I can't do well, however, is come up with names. Therefore, I'll ask my readers, you guys. I'm having trouble with five OCs' names, specifically. These five will be used not only in the new fic I'm writing, but many more, current and future, hopefully.

First, a little backstory for the five. They will be the incarnations of Good (female) and Evil (male), and their three children, the Lords (or Ladies) of Time, Space, and Matter (born in that order). Soon after Matter (who is definitely male), is born, he creates life as Equis knows it. Evil, seeing a chance to gain an upper hand in his fights with Good, fathers a new, stranger creature: Tirek. In response, Good leaves, taking Time and Space with her. Matter is left alone, without either parent to raise him, and starts to go insane, eventually taking up the name Discord, Lord of Chaos, his form twisting to match his mind. In the meantime, Space has two children of its own, the diarchs of celestial objects: Celestia and Luna.

So, what I'm asking is simple - name the five OCs; Good, Evil, Time, Space, and Matter.
