I wonder if "Zera" is still around.

Even if she's an unconscious part of it, she's still part of Mavis' magic. So has she been sealed along with Mavis other magic or did her being the product of something subconscious make her an exception from what Invel did to Mavis? After all he didn't directly seal Mavis' magic, but rather her ability to think about performing a spell.
