Solaris

Solaris in my theories:

Solaris might be a civilization/faction whose role is to serve justice and peace around the server. They capture Exiled after massacring the village at the end of the 2nd episode which probably mean they're here to stop disturbance from occurring or appearing in Island Realm.

I think if it got a look or a certain design, it might be looking luxurious or rich. But they also could be looking rusty and poor. I prefer them looking luxurious and vibrant in my head until they appear in the 3rd episode.
