The Imperial Army had set up a defensive line inside the grand hall.
The soldiers dug up the ground tiles, filled them with special soil, planted squirming grey worms, and poured a viscous yellow-brown liquid on them.
Within three minutes, violently swelling grey bulges rose from the ground, continuing until they grew into perfectly square "stone dunghills".
This was the Tatis Empire Army's unique bio-crafted building - the Gray Worm Barrier.
