Frill is a Dire Voxibell, and people often mistake her size as threatening; but Frill is a loving woman. She adores her smaller husband, Nox, and her even smaller child, Echo.
She lived a lot of her life in the Ocean with her 'pod', the family she grew up with - All Aquarian Voxibells. There was an incident that caused the Pod to be partially infected with the Werebeast Curse, luckily Frill managed to not get cursed from a young age.

The curse caused a rift between her and her older brother, Kraken, which led to the two of them righting and caused Kraken to attack Frill onsite at all times.
Frill unluckily ended up infected with the Werebeast Curse in the end, She can control it for the most part, but will lock herself and her son away whenever the Curse raises it's head...
