Freya

FT1!Frisk
After falling down to the Underground as the seventh human soul, Queen Toriel took her in before the Stygians could even reach for her. She was named by the Queen as Freya Licht Mercy Dreemurr, her daughter, the light princess of Lux. Freya was ignorant of the so-called darkness, enough to be considered as pure and merciful, but curious, and independently fierce.

FT2!Frisk
She was the Queen of Lux, as mentioned in the story’s Prologue, but was known as dead due to an accident occurring after an attempted invasion and assassination of Stygia.

FT3!Frisk
The reset took everything back to before the war between humans and monsters even occurred. However, the Light of Determination present in Lucy’s reset somehow caused Frisk’s age to freeze in time, making her an adult on the next timeline. She does not remember anything that occurred before, not until Sans arrives to her aid.
