Dyon's fingers raced across the keys, his passion growing as his emotionless eyes seemed to flicker with inexplicable feelings at seemingly random times.

The dao heart was a complex aspect of the martial world. The techniques for cultivating them were so important that they stood in a category of their own even compared to the other core teachings a sect might have. And, even then, only the top-most sects and clans would even have the worst of dao heart cultivation techniques.
There were nine dao hearts that reigned supreme over all others, while all remaining dao hearts were lesser evolved forms of these nine.
This structure was a saving grace for many transcendents who might not have been lucky enough to come from clans with these hidden techniques. It gave them the opportunity to evolve their own.
