You are a human child, working for the Agents at INNOVA after meeting them... at the floors bellow you were collecting parts for Chekhov...

You then grabbed out a document and read it

The Document's Description: “The subject appears to have two stages. Each varies drastically in appearance. Information is sparse, leaving a less robust description than typically preferred. Stage 1 can be described as a complete, black silhouette of her agent form, with the exception of its pendant having a magenta glow. Stage 2 is observed to have a much larger figure with a quadruped posture similar to its counterpart, Infected Copper, however, measurements cannot be taken due to its nature. It appears as a skeletal single-horned equine with a crescent shape attached to the end of its horn. The legs are unguligrade and disproportionately long. The subject's pupils seem to flicker into a target mark during chase.”

You then eyed at a highlighted word "Behaviors" which a red writing (likely written by Chekhov) that says "EXTREMELY IMPORTANT PART!!!" followed by a sticky note that reads

The Sticky Note: "Please read this kid... Please... **BE SAFE... And Keep Phantasia and Copper safe too..." -Chekhov

The Document's Behaviors: “Unlike other entities, the subject seemingly only appears to agents that have suffered from some level of physical damage. Seems like the subject will choose a random ‘target’ every so often out of everyone injured on the expedition. Alternatively, she can also be seen on cameras. In its passive state, (stage 1,) it will pursue its target, attempting to heal existing injuries the same way agent Phantasia does. In some cases, the attempts to heal are successful. In other cases, the subject contorts into its stage 2 form. Once the subject transforms into stage 2, it will not revert back. The subject will continue to roam towards the same target, ignoring all others. Cameras have shown the subject increasing in speed the longer it chases the target. It appears to only slow via finally reaching, and hurting its target.”

You sighed and closed the document... and you walked off... and you got slashed by an infected, taking damage and you ran off... you sighed... then you heard... calming music...?

"..."

She appears... It was... Phantasia? Is it her?

You sighed causing you to say "Oh... It's just Phantasia

You approached her, and when you asked her for a heal...

The music distorts... she reveals herself in Phase 2... it wasn't Phantasia... it was... INFECTED PHANTASIA..

Distorted Lullaby Music...
