Getting to the den of Iron Claw the Wicked, wasn't a journey that was too lengthy. It was a seven hour walk, and since the platoon set out at the crack of dawn, they got to their location by early noon. Now they didn't rush into the dragon’s nest directly, no, because after such a long session of walking, everyone needed an hour to regain their strength.
The need for a break was one of the things that held them back, while the tactical disadvantage they had here, was the second thing. The platoon had to climb up a rocky mountain, just to get close to the nest here.
The mountain featured many cliffs, and edges that could kill a panicking person faster than the dragon would. There was a cliff that had a huge, deep river underneath it, so someone might get lucky enough to land on the river upon conflict, assuming that they could withstand splashing on the river after falling from a two-hundred meter tall cliff. The latter was the most comfortable death upon impact.
