Phase 1 is the setup, with the destruction of a research facility in Nevada.
Phase 2 is the investigation, where they find the source, the enemy, and the problem. The roleplay here will involve convincing Archon to snap out of her coma, because it is discovered that she is fully aware of her comatose status and would prefer she remain in it, or better yet, to finally die.
Phase 3 is when the Archon's life takes yet another spiral downward. She is found to be homeless and she once again is attempting to seek death via starvation or stabbing. Neither one is working and while she cannot die in a permanent death, she faces constant starvation-related pains. The roleplay here involves convincing her aim her hatred outward rather than inward.

Phase 2 and 3 involve a lot of conversation-related roleplay, much of it attempting to raise the spirits of a depressed and frightened woman. These will lead to...

Phase 4, wherein she accepts her lot in life and begins to aim her fury towards a commonplace enemy; the PSI.
Phase 5 is when she more or less becomes a kind of demigod, where her actions are deemed worthy enough by higher powers to take up the moniker of "Archon". She is then blessed with a nearly alien-like form and radiant armaments.

The explosion melted most of the facility but there will still some parts untouched. However the effects were still seen throughout.
The center of the explosion was difficult to get to due to a mountain of collapsed rubble, much of it from surrounding buildings caving in after the foundations no longer existed.

This process took several days, in which the death toll reached five hundred, and the injuries count reached a similar number. News began covering the loss with frequency, and memorials were erected.

During the dig, there was a mounting evidence against the PSI organization, which began to make sense as the facility was researching dreams. While the bulk of evidence was effectively destroyed, other parts of the facility still had relevant information regarding the incident.

When they reached the source of the explosion, PRIMUS were surprised to find a woman in the rubble, entirely nude and dirty from the rubble, but otherwise unfazed. Her body also had pulsating lines of energy within her skin, permeating throughout her body.
She was immediately dubbed relevant and transported to a facility in Millennium City.

She was about impossible to directly identify without further information. Throughout the Dream Center there were only reports of "Subject #474" and "Project Understanding". A lot was missing due to the destruction, though PSI is mentioned and investigations immediately began and the organization made several suspicious movements after the incident.

The woman was deduced to be the Subject 474, and was discovered to be in a coma when attempts to wake her proved fruitless. She was sent to a special hospital in Millennium City, a specially guarded wing while PRIMUS investigated further.

While the technology from the Dream Center was under study, PRIMUS contacted powerful Psions in order to enter the woman's mind in order to discover the secrets behind the incident in Nevada.

When her mind was entered, the hired heroes discovered a ghastly sight. The ensuing realm wasn't so much disturbing, but more... wrong.
They were treated with a ruined metropolis with a black, red, and purple sky. A supernatural wind blew through the 'city'. Upon exploration they found a large statue of a large woman bound in armor and chains, nailed to a chair befitting of her size. Nearby was another woman, smaller. She was identified as being the woman in the coma, yet vaguely deformed. She was missing the area surrounding her heart. Ribs were shown, but no muscle, organs or gore. In place of her heart was a black mass of pulsating energy.

A long discussion ensued.

The armored 'statue' was revealed to be a sentient soul - hers.
The Armored Soul is what speaks first. It is polite in interacting with the mindreaders, she introduced herself as the girl's anguish and fury. That the explosion was because her soul burned brighter than most and PSI's experimentation accidentally detonated it. In the girl's grief of the devastation, she "locked" her soul away and essentially put herself into a comatose state so that she wouldn't hurt anyone else.

Many other justifications ensue. She does not want to enter a world that she feels dislikes or hates. From religion, to gender, to orientation, she feels most of the planet is politically against her and does not want to help save a world full of problems.

She also reveals the true source of the problem - The Dream Center. A facility designed by PSI (Though she did not know this at the time), she was effectively kidnapped along with hundreds of others. Beneath the facility was a prison-like sector where everyone was forced to utilize experimental technology. The idea was to explore the complex minds of humans. Since mind reading is two dimensional for many - like reading a book or watching a movie. And that's just for experienced Psionics. The Dream Center sought to make mindreading three-dimensional, stepping directly into someones mind as if walking through an amusement park and actively taking part in the subject's mind.

However the technology was imperfect and led to severe mental degradation. Her resistance just made it worse as her mind and body wore down further. She overheard conversations of further trauma to be inflicted on her and her soul acted out, leading to the explosion.

It takes some convincing (Which takes a combination of logic or clever personality manipulation) to break through her anger and indifference. In the end, she decides to awaken.

The PRIMUS doctors thanked the heroes and told them they would take care of the woman in days to come, though she was diagnosed with Post Traumatic Stress Disorder.

After some investigation, the heroes discover that the woman is now homeless and wandering the streets. She thinks she has unofficially joined several gangs but can't keep track, she just does what she can to not be accost on the street so she can avoid hurting anyone.
After some discussion it becomes known that she is essentially trying to starve herself to death and it isn't working. She feels the pains of hunger but it isn't giving her the satisfaction of the "long sleep" as she refers to it.

Once again, a combination of logic and personality manipulation was needed to snap her out of it.

The end result is optimistic - she feels the need to pay PSI in kind for the horrible things done to her and decides to register as a hero. She takes up the moniker "Archon", in relation to the lore of Archons being soul-infused leaders of men.

Archon still suffers from PTSD but with a combination of medication and metahuman-related therapy, she becomes healthier in time.

She finds an appropriate outlet with Hero work, training to make her attacks much less lethal than the last.

She has accepted her current log in life and works towards wiping PSI off the map.
