Discovering Skywhal was a challenge in the early days of Espercorp. The only evidence we ever saw of them were odd ambient signals because they spend most of their time migrating from storm front to storm front, far above where our early radar detection would reach. However, once we extrapolated that Espers could exist well above ground level, discovering Skywhal was as easy as visiting the nearest rainstorm. Of course, that didn’t turn out to be easy at all, but that’s a report for another day.
Skywhal are wind Espers that take on the physical traits of condensed water particles. The shape that they take can only be said to resemble that of a whale, though “shape” is something of a misnomer because it changes so often. Skywhal have been noted to appear as formless clouds , or to even take the form of other objects, such as animals and vehicles. Their most common shape, however, is that of a whale (blue whale is most common, but everything from sperm whale to orca has been noted at some point). These shapes can range from small to incredibly large, since Skywhal can alter their eV density along with their contour.
A fascinating aspect of this lack of permanent shape or consistent density is that Skywhal can “overlap.” They can pass through one another like a gas, without mixing together. They can even coordinate to create larger formations and shapes using what I am almost certain are complicated sound patterns (on which I will elaborate below).
In the wild, Skywhal travel in great pods, migrating with storm clouds and other weather patterns. Pods of Skywhal appear consistently on cloudy days, usually in groups of up to a dozen.
In large storms, however, their concentration grows enormously, creating super-pods of upward of 100 Skywhal at a time. As you can imagine, the level of cloud cover over Earth does not remain constant, and we speculate that the population of Skywhal does not either. We are still hypothesizing as to how to account for such sudden fluctuations.
One theory I’ve considered is that storms are generation foci for new Espers, “breeding grounds” for lack of a better term (though Alister will be upset if I don’t clarify that we still cannot conclusively say that Espers breed at all, being that they have no apparent gender). Essentially, storms serve as congregation points for air and water Espers, and the high density leads to the dissipation of air Espers into water Espers. This would go far in explaining the relationship of Espers to actual weather patterns, but we will need more data from our Agents in the field before this can be considered anything but a fanciful theory of my own.
The Skywhal in our care have proven to be extremely intelligent and excellent mimics. They recognize scientists and caretakers, and a few staff, myself included, have formed relationships with them. My own Skywhal (which I’ve affectionately dubbed “Fluffy”) greets me by taking the form of spiral, spinning like a sideways tornado and flying through me. One particularly versatile Skywhal has recently taken to mimicking our faces. It took some time for us to recognize the behavior for what it was, but once we saw them through the Esper screen, the likeness was unmistakable. More often, however, Skywhal will imitate the shapes of other Espers in their enclosure .
While we currently have no means of “hearing” the noises that Espers make, they clearly emit vibrations that mimic sound within the thymosphere. The patterns of such sounds are incredibly interesting. Their fluctuations resemble the low rumbles of thunder with an ambient staccato of rainfall. I am certain that this is a means of communication between Skywhal, and further study of it would be extremely rewarding. Perhaps the communication of Skywhal might even help us to predict weather patterns!
Note to Scott: Could you find some way of converting Esper sound into real sound? It would be so much more interesting that looking at page after page of frequency read-outs.
