I have one main sona (Froststream, which is my avatar) but I chose the 'I have more than one sona and they're all equal' because I don't want to consider the many, many other ones secondary. XD
Froststream, Sakani, Amethyst, Hazelcloud, [InsertNameHereBecauseIHaven'tDecidedYet], [AnotherInsertNameHere], and Shadowclaw. That's not all, but those are the ones I can think of off the top of my head. And yes, two unnamed ones. I just can't find a good name for them, but i will soon.
