Morose, adept

Morose - someone who is morose is miserable, bad-tempered, and not willing to talk very much to other people

I generally don’t like morose persons: not only do they feel miserable themselves, but impose their bad attitude and emotions on anyone who dares to talk to them.

Adept - very proficient in something requiring skill or manual dexterity

The Adept of the Swords stood in the center of the training ground with his left leg firmly standing on the ground, his right leg bent and bare foot pressed against the inner left thigh. Man’s eyes were closed, body leaned slightly forward, hands stretched down, right one holding a sword its point outward. The adept was still, motionless, unmoving, only the point of his sword was making tiny up and down movements agreeing with his heartbeat.
