Songstresses are technically the summoners/callers of Caelum, is why I ask the question. As Lumenaria goes up in level, she'll begin to present more and more of Sigilyph's powers in her own abilities (like imitations, not the actual power). For language though, I'll probably keep it to the Caelestis knowing a bit of West/Northwest Common and primarily Bird Common. I'll add in that to her CS.
