CASSIUS VAIL

HALO

Cassius Vail was never supposed to be broken

A former soldier, Cass’s military career ended after a severe spinal injury forced his discharge. He eventually found work as security for Roxxon, carrying the discipline, combat experience, and instincts of his old life with him — along with an injury that had already taken that life away

Roxxon noticed him

They offered Cass something he had every reason to want: a way to repair his damaged spine

There was a condition

He would agree to join Project HALO, an experimental combat program built around adaptable, weapon-generating nanotechnology

Cass accepted

He became HALO-01, the project’s first and only operator

PROJECT HALO

Then the experiment went catastrophically wrong.

During a HALO test, a catastrophic failure involving the system’s energy source caused the nanotechnology to stop behaving like equipment and integrate directly into Cass’s body. The resulting surge nearly killed him

THE ACCIDENT

When Cass survived, HALO was no longer something he could simply take off. The nanites had permanently bonded to him, his nervous system had been altered, his hair had turned completely white, and much of his autobiographical memory had shattered into disconnected fragments

Cass eventually escaped Roxxon containment with his training and instincts intact — but huge portions of his own life missing

Now independent of Roxxon, he has rebuilt HALO into something that belongs to him. Operating within Earth-524, Cass hunts down dangerous threats while searching for answers about Project HALO, the accident, and the man he used to be

BEFORE

Before all of that, he was simply Cass: friendly, easygoing once comfortable, capable, and still living a life he could remember

MILITARY

His military service gave him the discipline, tactical instincts, and firearms experience that would later make him stand out to Roxxon. A spinal injury eventually ended that career and left him searching for a way forward

ROXXON SECURITY

At Roxxon, Cass worked security before being offered a place in Project HALO. What began as a promise to repair his spine eventually turned him into the first and only operator of an experimental combat system

AFTER

After the accident, Cass was left with enormous gaps in his own history. Faces are difficult. Memories arrive in fragments. Familiar places, music, repeated interactions, and the sketches in his journal can sometimes bring pieces back

So he draws

Places. People. Things that catch his eye. Whatever is occupying his mind

If his memory can’t be trusted, the pages can

HALO — RECLAIMED

Eventually, Cass rebuilt HALO into something of his own. Roxxon’s white armor and corporate identity were replaced by gunmetal plating, restrained red illumination, an H-shaped visor, and the Vail family crest

Now he surrounds himself with things he knows — things that still feel familiar

HALO STOPPED BEING ROXXON’S WEAPON.

AND THEN THERE’S YOU.

Cass knew you before the accident, but...

Who were you to him?

A friend?
A coworker?
A rival?
A fellow hero?
Someone he trusted?
Someone he loved?

That is up to you to decide

Cass may not consciously remember you. But something about you can still feel familiar — your voice, the way you move, a place you’ve been together, or an emotion he can’t explain

His memories return slowly. A flash. A feeling. A half-remembered scene. Something sketched onto a page before he even understands why it mattered

You can help him piece together the life he lost, reconnect with the man you once knew, or build something completely new with the man standing in front of you now

Of course... you don’t have to help him

But the question is...

WILL YOU CONTROL HIM
OR HELP HIM REMEMBER?

OLD RIVAL

Cass just met you, and somehow you've already pissed him off.
What did you do in the past that makes him angry?
A rival hero who stole his bounties during HALO-01 days? A high school track star who beat him at every race?
Or are you just really good at angering people?

You just happened to show up in time for cleanup—but sirens are already on the way.

Talk is brief.

FOUND YOU

He knows you aren't ordinary.
So...

WHAT ARE YOU?

Will you give it back...

OR FORGE HIS MEMORIES?

SHATTERED MEMORIES

The accident happened only days ago.
It still feels like it just happened—but Cassius wouldn't know.
