The is story is well written. The action flows and the characters are nicely developed.

Some Suggestions:

You might consider dropping this down to add to second paragraph: >>It was on a cold night when a curious youth named Thadeus received a special visit.

Maybe change: Brea gave a fearful glance to Thadeus and jumped to her feet and gave a distraught command.>>Brea gave a fearful glance at Thadeus and jumped to her feet to give a distraught command.

Maybe change: Suddenly there was a knock on their wooden door >>There was a loud knock on their wooden door

Not sure if "sulked" is the word you wanted to use.... >>Brea sulked onto a chair

Double word, maybe use another, or cut it out, sometimes adverbs can be redundant: At the far end of the hall was a white stone staircase that led to a large golden door that was obviously the king’s chamber. It was obviously very heavy which Thadeus thought why there were four strong men in front of it.

Three things: Capital T (t)he guard yelled as he and the other three <slowly> opened the door just wide enough for him to pass through. Thadeus was awestruck as his eyes beheld the king of Ithia sitting in his grand throne room.” Drop parenthasis at end.

Maybe reverse: Crunching sounds were made as the horse trod over icy grass.>>I.E. The horse's hooves crunched as they trod over the icy grass.

Need a capital (He) “…and stay away!” he yelled in the direction of the dragon.

Maybe revise: They were closing in on him, slowly like living corpses.>>They closed in on him like living corpses.

Consider dropping (still)> Thadeus did not tarry but mounted his horse and rode on still.

Reverse sentennces: Then that peculiar feeling burned within him. It was as though something was calling him. Just as he emerged from the forest an intuition drove him on. >> I.E. Just as he emerged from the forest,that peculiar feeling burned within him. It was as though something was calling him.

Maybe revise: It was an amazement how fast he was going >> It was amazing how fast he was going.

Maybe revise: courtyard where the dragon holds were >> dragon hold courtyard

Remove (as)>> other specters managed to flee in as the wind like fluttering rags

You might check your adverb usage, such as: carefully, suddenly, etc. Either they can be dropped as the sentence explains the action, or the sentence needs to be revised. <<I speak from experience, as a semi-reformed "over adverb user". <grin>

You have 2 typos (I) in place of (in) that I saw on the first read, but now can’t find… Good hunting…

I like the story, it was a good read.
