Alrighty, more questions:

So, for Ki. From what in read, for the majority of people, this inner energy is mystical but not something unheard of. Most soldiers / warriors think this is gibberish work and is not worth the time and effort to gather. Does it mean that some that uses Ki in a martial manner that surpasses a High ranking soldier's with nothing more than his fists and kicks would be an impressive show of might?

Also, I would have my character be a Spiritual Guide and Servant for Erasmus, always present in the court to do his King's requests and always silent. I would keep him as more of a secret protector Erasmus has in his arsenal (Since he is armed while wearing nothing more than robes.)
