"Whats this do?" Asked the visting Human.
"That," Dugfar replied. "Is my- Wait! Don’t tou-"
...and with that they were buried alive.
The proud dwarven Captain Dugfar stood atop his mighty machine of magic and stone looking down the mountain they had just emerged from; letting the wind whip his beard over his shoulder… "This is a proud day for the Dwarves!" He bellowed. "...and this is just the start!"
The players see a small shrine to the local nature deity just of the trail. Before they even approach it, they can smell the foul stench of rotting meat. If they inspect the shrine, they can see it has been desecrated by rotting organs in the last few days. There is no mistaking it for an obscure ritual, the organs are thrown everywhere, not left in specific places as in sacrifice.
If the players try to clean the shrine, they will soon find it has been boobytrapped to fling sharp splinters covered in the rotting gore in every direction. While only doing a few points of damage, they injured players will likely take sick soon unless they get medical attention.
