Verily ‘tis a romaunce of exceedinge highe vertue! And do greatly appercieve therejne, bothe fauncy of imaginacioun unpareilled, and stronge allegorie of hidden lore! Of worlbuildynge and allegorye eache in chaine.
Modern translation: Not only does it look fantastic, oozing with atmosphere, but also gets the structure just right. I love the idea of a piece of FRUIT somehow acting like this Grail item, it feels so plausible and yet weird at the same time.
Also I am total sucker for in-character themed disclaimers. Amazing work!
