intro to characters

I was 15 when the virus out broke. Everyone scattered from the small yet rich town of paynters paradise. The richest of the village people received the news first, the middle aged adults grabbed their children and flew to an exclusive island. The elderly who spent their life gaining lojin in the rich town were given mercy and the rest of us stuck it out until we were bitten.
Along the way the group of five friends constantly seems to be expanding yet decreasing as they find out that the undead is not the only thing to fear.
