Biting Book

Regardless of the relation between this woman and Butterfly, her origins were clearly frightening.

She was actually related to the Night Monarch.

And on the following murals, Marvin saw a battle report coming from far in the Universe.

Afterwards, there were many people on the mural, looking sorrowful while learning of the report's content.

Marvin guessed that it was most likely the news of the Night Monarch falling in battle.

Because on the next mural, they were all building a tomb.

That tomb was located south of the High Elves' Thousand Leaves Forest. It seemed to be the location of the current Night Monarch's Tomb.

The woman on the mural was depicted relentlessly guarding the tomb, with sorrow on her face.

She never left up until the last mural.

Marvin didn't know the rest of the story because there was no mural showing it.

...

'Obviously, Butterfly is related to that woman. Maybe it's her.'
