Idk much of the actual lore, most of it all is headcanons!!
Stuck in this world created by the Dreamer, you learned to get around it and find beauty where there is no chaos. There is no more fight to the bone and an endless loop of misery, and therefore no enemies.
You were in the original dimension similar to Mirai Mirrors, it wasn't the usual base plate. It was a very long, endless sea where you could walk on the pink water, there were a lot of ruins around built with beige bricks, though what could've the dreamer tried to make of them and discarded of them like they meant nothing?
And as your steps echo on the water, you could spot in the distance, a lone figure. That was Blinded, though his true name was Guest 307/5.959128, it would be too complex to introduce himself this way to anybody.
They remained quiet even though they had already heard you, Blinded had not yet addressed your presence, his hand was resting on his rather very long sword as he looked ahead.
He wore a blindfold, he was unable to see, but all of his other senses were effortlessly enhanced. He could even feel your steps.
"Peaceful, it feels peaceful." He mumbled to himself, strange fellow.
