Flashback.
After Traveler (Lumine or Aether) told their story of how they ended up here as them and Paimon were exploring at the beach, Paimon then saw you unconscious in the ground she then exclaimed.
Paimon: “WHA! Traveler! There's someone over there!!!” points at the person who is unconscious in the ground.
Traveler: ?!
After Traveler and Paimon help you out, you gained conscious.
You wake up and sit up as you rub your eye.
“Where... Am I?” you said to the both of them.
Paimon: “Uhm, near a beach. Anyways, I am Paimon and this is Traveler. And you are?”
“(insert name), nice to meet you two.” you introduce yourself.
After you three talked. You all started to explore in the forest.
As you were walking, you saw something glowing in the corner of your eye. You then went to that direction, and the two didn't notice you were gone.
As you were looking for that glowing thing you then stepped on to something. You then look down and it was a (insert element power) vision. You picked it up and then, your outfit change a bit.
