The wolves are anything but fire proof and the trolls aren't exactly fire proof either when Liz goes to let them have it. The trolls up front along with the charging wolves are burnt to an unpleasant crisp.

Its the grumble from above that has the best luck as a wall of fire pours down from above on the remaining trolls and wolves. There as clear as day is a massive golden dragon.

With the threat gone for now the dragon goes to settle himself down on the ground. "I see there is more of you here." The dragon speaks and it begins to stalk towards the party of humans and the Time Lord in question.
