*Spoiler Alert*
I am not entirely sure just how far you got, but after you find Ellex's caravan in the mountains you eventually square off against Lord Bullmont and his group. After that (and a cutscene), you end up in Storm Point where you will defend a bridge against an increasing number of attackers (3 waves, each wave gets an additional enemy every turn) with the last wave being one that you only have to survive for 5 turns. After that you get a dream sequence, then you have the Storm Point tunnels to navigate and one last final boss, and then the final cut scene.
