Beneath the sands of Dalia, their exists a beastly, horrifying creature. The Tayan.
The Tayan is an antlion like insectoid creature, that buries itself underground, and waits for prey to fall in its mouth. The Tayan is a huge creature, with a mouth big enough to swallow an Earth grizzly bear whole. Once eaten, prey rolls down the Tayan’s throat, into its stomach.
Unfortunately for those eaten, the Tayan was genetically engineered by an ancient alien race to cause excruciating pain to anything that falls into the stomach. Prey can be digested for up to 5 years, while their entire body is slowly eaten away. Small tendrils act as a dialysis machine for the Tayan’s victim, keeping it alive so that it can feel suffering.
Native Dalians, who are very primitive, often used the Tayan for sacrificial purposes, throwing slaves, criminals and captured enemies to be eaten by the Tayan. In the 25th century, when the first FTL species discovered Dalia and the Tayan, and intergalactic crimelords started sending their enemies and rivals down the Tayan's throat.
Guardsmen have to push victims into the Tayan’s sand trap, so that they could fall in and be eaten. Here is my question: How could the guards safely get the victims into the Tayans sand trap, without them fighting back?
It would make the most logical sense for would be victims to fight back against the guardsmen, and maybe even try to get some of them to fall in, so what would be a good method to safely get victims in?
