Dragon Quest VI: Realms of Revelation/Murdaw's Keep

NOTE: The Hero character will be referred to by the name of "Rex" throughout this entire walkthrough. This is because his name was depicted as レック ("Rek") in a screenshot on the official Japanese website. Said website was on the DS version, and the Hero names listed on their screenshots of Dragon Quest IV and Dragon Quest V were "Solo" and "Abel" respectively. These are the canon names for the heroes of both of those games, so it follows that the name listed for the DQ6 Hero would also have a certain level of canonicity behind it.

That said, "Rex" is a name that works far more naturally in English, while still being almost the same.
