Deep in the pyramids scattered all over the nightmare desert, there were several interconnected spaces called hot pots.
There were breeding pots for the myriad creatures in the desert. Guilliman had once seen these place when he leapt through the first warp. And later on it became the prime target of the armies higher ups.
They had raided these pockets time and time again, and time and time again they had failed losing several members of their teams.
Finally around several months back they were able to isolate one of the mothers inside the hot pockets and attempt to kill it.
It was a tall order but they tried anyway.
this was a great abomination, a walking calamity at the chieften rank!! Their efforts yielded absolutely nothing. Neither of the three A ranks shelter leaders yielded a single victory.
So they made a long and far fetched bet.
The first to kill the serpent would lead the army as the chief of war.
Unknown to them, another party had taken this bet to heart.
