You probably missed it, but i inserted an IN for you and other players coming in late.
A short bit back I hopped in and out of FairyTail before joining the brawl. (quite literally)
At that time i offered anyone who wished to help "protect magnolia from a monster" had the option to get a free ride with me.
I noted OOC that anyone who came in later can just start at the edge of combat and say they took the ride.

Jollan's right though, the battle won't take much longer.
His suggestion to go bother Doge is good, lots of interesting story opportunities there.
