Khaldos

Khaldos were an ancient race of massive pitch-black dragon-like creatures that inhabited Western Gerontas before and during the Monolith Era. They were the first intelligent race with an understandable communication system and an organized tribe of sorts. Their historical timeline is unknown; it has been theorized that they somehow were also affected by the Monolith, although this is pretty poor based theory, as they weren't near the Monolith when it appeared (although they might be more sensitive to the radiation of it).

Appearance
Khaldos are pitch-black scaled, massive-sized, long dragon-like vertebrate lizards with a long neck and spiky tail. They have golden eyes, and they have a sharp-toothed mouth size of 2 horses. Some individuals have been known to be born blue or red, but these individuals have been banished and abandoned by their kin.

Personality
Khaldos are lustful, greedy, envious, aggressive and proud creatures and naturally almost completely unable to be reasonable with other species. They are unwilling to help or even leave alone anyone they don't see benefit themselves, and have no sense of empathy inside them. They are known to kill each other just out of boredom, and kill and devour every living being without hesitation. They are however, honorable, and always keep their word and never lie. They are also intelligent, and not easily distracted or tricked.

Abilities
Khaldos are able to fly, although not too long distances, and some are able to keep their breath to dive long periods. They are also able to breath fire through chemicals in their stomach, and their scales are extremely hard and able to withstand extreme temperatures (known to survive from erupting volcanoes). Their most amusing ability however, is that they are able to harden their scales and slow their body and brain down to the point they are able to sleep in super-hard shells for hundreds of years almost safely. How they are able to do this is unknown.

Their communication is also complicated: they send various electrical pulses to stimulate parts of the brain that form speech to understand each other silently. Through these pulses, anyone is able to easily understand their speech. The complicity of these messages is somewhat limited however.

Theories
Their firebreathing ability is known to work because of stomach acids or some other burning chemical component. Their wingspan is large, but as they are both heavy and armored, they cannot fly long distances.

Their ability to survive without air for long periods is unexplainable, but it is theorized to rather slow down extremely much than stop completely. As they go to their 'sleep-mode', where they create the inpenetrable shell of scales on them, the small holes where nostrils would be are known to inhale or exhale for months. The pulse heard from inside can be heard maybe once a month, too.

Their communication is known to work thanks to the electrical pulses, but how these pulses are sent all the way through the air unharmed to the exact part of the brain is unknown. Some have speculated that they would be more like high-pitched noises or something similar that ears could hear but not become aware of. These signals would still be sent to the brain and deliver the message.

Their 'evil' personality is thought to come from the fact that they were the most dominant race in Martio prior to the Monolith Era. They were used to 'rule', have power over other species, and when Theians came into existence, their place as the most powerful race faltered. They became bitter and jealous because of their achievements and intelligence. When the other races began to develop as well, their conclusion was that 'their food had become arrogant and imperious, trying to fight back'.
