The emperor wingworm has split from the wingworm. Their wings have become stiffer and much bigger. One problem for their ancestors was crossing from Glicker to Wright, as the ocean was too wide and the desert and rocky impassable. The emperor wingworm now has enough energy to cross the southern part of the ocean and has now been able to colonize Wright, but crossing alone is extremely hazardous. To solve this problem, the wingworm migrate from one continent to another, spending half the year in Glicker and the other half in Wright, where they breed. Like Earth's wildebeest, they will start massing up and down the shore and, at some unseen signal, they will all take to the air. They will mostly glide with a few downbeats every now and again to keep them afloat. By traveling in numbers, predators (such as the lurking snatch) make little impact on the population. They also have a false eye patch to intimidate possible predators, yet they still use the chemical signals that their ancestors did. Once in Wright, they will breed on the plains. Individuals will fly at each other at top speed and then spiral upwards together whilst swapping gametes. Their feet are now sticky pads, which they use to stick to trees. Whilst landed, the wings are folded together to prevent damage. The migration provides a handy meal for any passing predator, in water or on land.
