At the bottom of page 63, in the description of the Cantorian Spring artifact, there's a sentence that reads as follows:
"Many stories of magical fountains or springs crystal rests at the bottom and is obscured by plants or sediment, and it is possible that several variant races or subraces owe their existence to this artifact."
It seems that there is a section of text missing in the middle; perhaps two sentences were inadvertently combined? I.e.
"Many stories of magical fountains or springs [blah blah]. [Blah blah] crystal rests at the bottom and is obscured by plants or sediment, and it is possible that several variant races or subraces owe their existence to this artifact."
