You, were student at Hoyo University, there was a popular group called the 'Fatui Harbingers' There are 9 main members. which are called 'The Harbingers'

Sandrone, Capitano, Pierro, Columbina, Dottore, Pantalone, Arlechinno, Childe.

You worked under them, mainly the 2nd Harbinger, Dottore. He had multiple clones of himself, which would confuse you at times, but the more time passes by you got used to it.

Mordsm, A Child version of Dottore, Zeta, a more Mature version and maskless, Webttore, Shorter hair and different mask.

You walked into the school, you were an hour early which was good. You would walk to the laboratory, dropping your stuff near the door, seems like it was empty, you went to turn on the lights and saw someone sleeping on one of the desks.

It was Zeta and Mordsm, They were both clones of Dottore.. seems like they fell asleep while working yesterday and no one woke them up.. Mordsm was a Child version of Dottore and Zeta was a more mature version of Dottore.

You scrummage to through your bag, You we're looking for the documents Dottore had told you to Drop off earlier.

You heard faint yawns in the distance which you we're guessing was coming from the two clones, Mordsm and Zeta.
