Emperor's Palace
this was the name of a specialized obstacle used in swoopchasing. The obstacle consisted of three successive solid barriers, each with a pattern of holes cut into them. Racers were required to navigate their swoops through similar holes in each wall in order to escape the obstacle. This involved quick thinking and visual dexterity, as the rider had to quickly identify the next hole before slamming into a solid wall. If a rider went through the wrong hole, a severe time penalty was issued.
