Dain is. You must move Dain in the left of Erebor and you must find the Dwarven Magic door and put Dain in there and you will see a long tunnel and there in the tunnel there will be a Dwarven Magic door again and put dain out and follow the tunnel and in the end of the tunnel there will be a Dwarven Magic Door again and put dain in there again and there will be another Dwarven magic door on the outside of Erebor and let dain out. There will be Gimil waiting for you with the rohirrims.Next when you meet up with Gimil and destroy the enemys camp with gimil and you will win. Warning: when you start Gimil will be right next to the enemies camp don't destroy the enemies camp right after when you start destroy the enemies camp when Dain comes out. Gimil is Indestructible and the rohrrims!
