Path of Dragon Fury

Barbarians who walk the Path of Dragon Fury come from villages exposed to residual magical energy from a dragon's lair that has leeched into forests, rivers and towns, unintentionally transforming the environment. Normally a dragon chooses extremely remote locations to create a lair, but some dragons have struck deals with tribes and clans to settle near them in attempts to create such warriors from childhood, although attempts such as these are often fatal.

The few who walk the path take on personality traits of dragons, becoming arrogant and acting superior to others when their draconic traits develop. Their rage presents itself as a powerful aura which can send foes flying and give them an edge in all aspects of life. Like dragons, those who walk the path value wealth, but their human nature allows them to break free from the primal greed of dragons if they so choose to. 

Draconic Retaliation

Starting when you choose this path at 3rd level, your rage draws upon the primal might of dragons. Whenever you are hit with a physical or ranged melee attack, you can use your reaction to produce a mighty dragon's roar. The damage you take from the attack is halved, and any enemy within 30ft of you who can hear your roar has disadvantage on physical and ranged melee attacks against you until your next turn. You cannot use this feature on the turn following it's use, if you are restrained or incapacitated.

Dragonsense

Beginning at 6th level, you perceive the world as dragons do. You can choose between two features, and you can change your chosen feature everytime you gain a level in this class:

Eyes of the Dragon: You gain Darkvision out to 60ft and can see through magical darkness. If you already have darkvision, you increase your range by 60ft. 

Dominate the Land: Your Speed increases by 10ft. In addition, you incur no penalties when travelling through difficult terrain and can use Stealth when travelling at a normal pace. 

Crushing Presence

Beginning at 10th level, the influence of dragons has overtaken your body. As part of the bonus action used to rage, you gain a booming aura, pulsing with energy and producing a noticeable pressure. Once on each of your turns, when you hit a creature with an attack, you can manipulate your aura to forcibly move your target 10ft in any direction. If your target is pushed into a wall or ceiling as a result of this, they are crushed between it and your aura, taking force damage equal to your proficiency bonus.

Beyond Human

Starting at 14th level, the draconic influence inside you reaches a boiling point as your Crushing Presence aura becomes tangible without your rage. Before you perform a skill check, you can add your rage damage modifier to the roll. You must declare your intent to use this ability before performing the roll, and you can use this ability a number of times equal to half your proficiency bonus rounded down.
