Hill didn't think of insects for no reason.
Aesces's approach to making the world increasingly arid, while indeed weakening the power of Water Deities, also harms nature, especially the flora and fauna that require water.
And in his past world, there has always been a saying: after a great drought, a great disaster follows.
Because of Aesces's attributes, disasters like earthquakes are unlikely, but… insect plagues are prone to occur.
In the inertia of the Fantasy World, once an insect plague arises, it might attract the attention of the ancient Evil God, Worm Walker Kaiwos.
This ancient Evil God was imprisoned by the combined efforts of All Gods of the Multiverse because of a legend: When Kaiwos breaks free, he will propel and guide humanity towards the final era, the mysterious Era of the Worm.
Of course, Aesces understood what Hill was hinting, so he directly replied that there are scorpions in the desert.
