*[About “Lagi” Dragon?]
By profession the Hero knows about “Living Weapons”, his knowledge about the Ancient Age ruins being far greater than that of general people. He sees the deformity as as sign of the legend of the Dragon so he has no doubts that he should raise the pup.18
Here in the village, there has recently been a variety of (deformed) Coolia and many of the villages have deep misgivings of the matter. [People have put forward a variety of sucessful ideas, and as above all things they are seen as an ominous symbol, they are to be killed at birth on sight] So wothout question it became the villages law. The Hero is against the law causing him to rear the deformed Coolia in hhiding.
[Ragi19] (Lagi) grew at several times the rate of the other Coolia and after a period of months was nearly an adult.
[Dragons] were the Ancient Ages weapons of war, a variation on the “Living Weapons”. Simply, if it is compared with the other mass produced “Living Weapons”, the Dragon lineage was a trail manufacture, so only a limited number of units were produced. Still, they were used for many purposes on the battlefield, because of its role guarding people they are inserted with consideration, their many additional functions hidden from view by their diverse forms.
Such information concerning the Dragon has been heard by the Empire although they have not been able to clarify it, not to mention the story all the more empowers the civilians.20
18 Although the text doesn’t explicitly say “the pup/Coolia, etc” I couldn’t just leave it as “He should be raising.”. I’d sell my granny if it turned out to be something else, though 
19 Like Randi Jyan Jyakku, kept for posterity.
20 The kanji used for “story” here, makes it sound almost like a religious foretelling rather than just an old wives tale, and where I’ve used “empowered” the original Japanese states “convert”, again to further imply that the Dragon is more of a religious saviour than anything.*
…That’s it!! Phew 
Thanks for everybody who still reads my hack jobs, because I really enjoyed doing it! If you guys can tolerate my level of translating, I’m happy to have a go at a few more. The “Old Diaries” mentioned by Solo Wing sounded pretty interesting, but if you guys can offer and reasonable suggestions then please do!
