What to expect from Lost season 1 fanfic

In my fanfic of lost, season on will not have flashbacks on the original cast. there are 12 characters based on lostepedia users. They will be receving centric episodes. The events are the same, but some parts are changed due to the 12 characters. it will take place during the first season of lost and end in exodous, where there is alot more fighting with the others and a showdown between Jack,Sawyer and Wade.
