Activation prompt is "queen_memory"
Other prompts to consider:
-"very long hair" or "long hair"
-"curled ends" (for hair), you can also try "curly hair" but I find that's less accurate as a description.
-"fairy wings" or just "wings"
-"white dress", "sleeveless" and/or "strapless"
-"white gloves"
-"armor" or specifically "shoulder armor"
-"forehead mark" or "facial mark"
-Any food prompt
