Very good and detailed! I especially liked the line, "... smoggy fog surrounding the tower that leaks over the calm waters ." Very nice description. You're painting a picture in my mind!
A couple things. The 'was' should be 'were' in this line. "It is also where Lancelot, Elyan and Freya were* put to rest..." The sentence is referring to multiple people. Also, 'fling' should be 'flung,' since its past tense (though I'm sure that was just a typo.)
Finally, you're missing a comma after Excalibur.
The sentence that follows is a bit long, so I might add a period and start a new one so it's easier to read. If you were to keep the sentence as the original, you would need a comma before and after "also known as Freya."
There are also a few more typos that I'm sure you just looked past (I do that all the time. It's like my fingers think faster than my brain haha)
Overall, I really like it! You are an excellent writer :) I hope to read some of your books!
