Legion, because there are many of us

He is that geek, quiet in the corner minding his own
Looks on, never a word just a friendly smile
Or a sputter of awkwardness in an attempt at conversation

He is that guy, adrenalin his fuel
His world a blur of adventure,
Violence his second nature
The smell of blood, a spur to his flank for more

The life of the party, that other one
Girls are his ambition, with alcohol no inhibitions
And herb as the cherry on top
Seeking the next big rush

To hold them all at the core
Lies the keeper to them all, and master to none
Guardian of the knowledge they are but one
Pulling each to their own, seeking separate identity

The keeper, sober and decisive, by psychology and meds he shall draw
them in...eventually
There is a limit to occupants of a mind, but they still fight it
They tire him, should he give in they all die
There is a limit to what the world takes as eccentric
And chains and cells is what they offer
He is one mind, one man, but many occupants; Legion
