Several moments pass as you wait for the gnolls in the small L-shaped chamber, listening to them bark and shout at one another behind the door. Suddenly, the deep bass note of a warhorn sounds, echoing loudly despite the closed portal between you and the gnolls. As the first note fades, a second sounds in short succession...you have no doubt that the horn can be clearly heard throughout most of this level of the Temple, and you are certain that the gnoll's reinforcements will soon be on their way.
