I really want to think about this (even though I hate angst so much cause it makes me cryyyy.)

If Lya one day woke up and the Devildom was gone...Lucifer was gone...Lucien was gone...the brothers were gone, everyone was gone...

The amount of fear and rage she would feel would be unbearably immense. It's difficult to say exactly what she would do when it could be multiple things. She could become so enraged that she destroys whatever realms are left trying to find her family. Or she could succumb to the unbearable grief of losing her son and husband, and be absolutely inconsolable to the point of her own demise. Both of these could even happen.

Or...she could keep a level head and figure out exactly what happened, why it happened and how to reverse it. She'd do everything in her power to get her loved ones and the Devildom back. Though I'll be honest, I feel like this option is highly unlikely. The thing about Lya is she is very slow to anger. She is a patient person. She is bright and bubbly and the sweetest girl you'll ever meet...until you mess with her family. So with an event like the Devildom disappearing (and presumably everyone in it) Lya would skip the kindness and grace and most likely fly into that intense rage because she's scared. Her family is her anchor. Without them, what reason is actually left for her to control her powers?

Something like this would make Lya have a complete psychological break and whoever caused it would pay. Dearly. You don't play with a woman's husband and child. 💔

I also want to add that Lya's magic usually has a bright, warm feel to it. It's very light and airy...almost playful...also very sparkly and pink. Her magic is a physical manifestation of her soul. But during a stressful event like this it would heavily resemble her father's power because of her grief and rage. So it would become very dense, dark and suffocating, dark purple to black in color. Instead of radiating her usual playfulness and purity, it would emit dread and fear to anyone that went near it, or her.

Thank you for your ask, Anon. 🩷🌸
