Ma Lu had seen a sandstorm before.
Earlier this year, City B had encountered one.
The city was shrouded in yellow sand, with PM10 concentrations exceeding 1000 micrograms per cubic meter at its worst, and the sky was a dim yellow, so much so that opening your mouth would fill it with sand.
However, a city's sandstorm is a whole different beast from a desert sandstorm, and as for danger, the former doesn't hold a candle to the latter.
"What should we do," Seta looked towards Boggy, "retreat, Captain?"
"No," Boggy decided after only a moment's thought, "if we head back to the city now, we'll completely lose track of the Six-armed Ancient Ape. It could easily reach the Giant Curtain under the cover of this sandstorm and attack the walls.
"We stick to the original plan, lead it into the trap, and aim to take care of it before the sandstorm arrives."
As the five discussed their next course of action, the Six-armed Ancient Ape on the dune noticed them.
