The rocks then move, configuring themselves into a archway-like gate, and within that gate is a mirror-like surface that leads to some kind of pocket dimension.
The prisoner within this dimension then emerges: a massive, hideous and utterly monstrous green troll with an armored hide. The troll smells fresh air, feels the sun upon its skin and basks in its new freedom... for a moment, before it immediately reaches for the nearest of our scouts, picking him up in one hand and crushing him to death with a single squeeze before biting his head off and chewing on it.

It leisurely continues its meal, sinking its teeth into the torso of the dead man, ignoring the attackers until its brings up a foot and slams it downwards upon the nearest scout, crushing him to death on the spot.
The remaining scouts flee, managing to make it home with the terrifying tale of the troll that emerged from the gate.
