Lukaud is a member of the shapeshifting lurin race. They have to enter their nest sphere, visible in the back of the image, in order to change forms. These forms are known as their "Aspects". These aren't all of their Aspects, but are the ones I've modeled so far and the most significant.
On the left is their natural Aspect, or in other words their true lurin form.
On the right is their gwil Aspect, which most refer to as Lady Jalae (short for Lukaud's title Obmunjalae, meaning "Master of the Voidplane"). This is their favorite Aspect and they spend the most time being it.
In the front is their suyen Aspect. They mainly had used it to visit an impoverished island of suyen and provide them charitable aid. Unfortunately, those islanders showed very little appreciation for their help, preferring to cling to their isolationist distrust of outsiders. However, one child named Yezukh'ay took great interest in Lukaud and their grand Voidplane vessel, and decided to escape to a new life during one of the periodic visits.
Finally, in the back is their Battle Aspect. It's the newest one I worked on. I had the idea of combining features of their gwil and natural Aspects and making them bigger and then give them wings, because why not?
You can also see all four have Lukaud's sigil on them in some way.
