Link Celtic.
Done.
Welsh is linked at second mention.
Fixed.
"constructed Elvish language" Link Elvish.
Done.
"Tolkien's Middle-earth including" probably needs a comma.
Repunctuated sentence.
"That was a complex pleasure" I'm unsure what exactly "that" is referring to here.
Edited.
"Literary Welsh" You could link the whole term instead of just the first word.
Done.
"Common Eldarin" Any applicable links here?
Added link in sentence.
"here in a 1910 illustration" maybe better as "shown here in a 1910 illustration"?
Done.
"Melkor" A gloss that quickly explains who this is would be helpful.
Added.
"invaded Ireland...burning their...fighting a..." You start the sentence in the past tense and switch to present halfway through. It's mythology, so past would be better.
Checked; it's grammatically correct.
"Uttermost West including" Comma
Added.
"is "so far" Undying Lands is plural, so should be "are"
Fixed.
"and Balor...glass" This clause does not make sense taken together with the part before the semicolon.
Rearranged sentence.
"The Sword in the Stone is broken" This sounds out of place, looks like it's missing the parallel of Narsil breaking.
Tweaked.
"the sword remade" Comma.
"the sword remade as Andúril" is a thing.
