Standard
Standard Umbra, these are just Umbra that haven't acquired any further social status among their society (listed below). These Umbra haven't accomplished or achieved any worthwhile feats to garner recognition as a higher class of Umbra, however, that doesn't mean that there aren't powerful Umbra in this category worthy of even competing against the higher classes. As well as Umbra that follow other professions that aren't solely focused in combat as their culture has built up in favor for.
Honorary
Honorary Umbra are Umbra that have garnered decent recognition for their accomplishments. These Umbra are seen as competent in combat, which is enough for an Umbra to be seen among the higher classes.
Elite
This term is applied to Umbra who have accomplished goals that goes beyond Standard Umbra capabilities. This title is usually given once an Honorary Umbra sparrs and wins against a Barada, the most fearsome animal in the entire Umbrian Rift. However, beating a Barada isn't the only path to achieve this status.
Conqueror
This title is given through official means. There are few Umbra that have achieved this status as they have beyond what the standard Umbra can do. It was once said that by being a Conqueror one can have the potential to attain power beyond that of the Stellars, the ancestors of the Umbra. They are the strongest the Umbrian race has to offer.
Even though Cloudans have their special traits, over time it's been seen as an issue for the "weaker classes." This would lead to Gifted Cloudans to accumulate a bad view from the other classes, specifically the Common Cloudans. This concern initially started with the Bound Cloudans in the past, as they would possess greater strength than they were if they were apart from an Umbra. It's been generally accepted that the initial fear of stronger individuals through the Umbra is what sparked to the sudden disappearance of the Bound Cloudans, along with the Umbra as a whole.
As time went on, this fear would later on develop to be targeted to the Gifted, resulting in the '08 incident where Gifted Cloudans would radically be terminated from the world from all countries, except for few countries that urged to close their borders and protect their citizens. This would mark these few specific countries as safe havens for the Gifted Cloudans to migrate into so they could go to hiding and away from being traced by hostile forces. But even then, accessing these countries was a challenge on its own.
In modern Earth, Gifted are hated worldwide. Many have been killed, but just as many have gone to hiding without a trace or a clue as of where they hid. But they aren't alone in their fight, as there are certainly countless Cloudans of all categories and of all social statuses who despise this outcome for the Gifted Cloudans, either out of empathy or because they have family or friends who are a Gifted.
