Before the day of doom arrived, he led his valiant Holy Warriors to slay the evil dragon Sabades, which was a level 8 peak subadult from the pure-blooded Dragon Clan occupying a small plane.
Arthur extracted the evil dragon's blood, refined its bones, melted its scales, and transformed its soul.
Using level 9 Holy Copper as the main ingredient, he collected countless precious materials.
He invited dozens of the most famous forging grandmasters from the Corona World to the empire's strategic site, the Tomb of the Holy Sword, where they forged day and night for a hundred years.
On the day when the exotic treasure was successfully forged, the entire Tomb of the Holy Sword was thoroughly integrated into it, merging as one.
And the Tomb of the Holy Sword was the birthplace of one of the Corona World's most important relics, the King's Relic.
The King's Relic.
That is what the wizards refer to as the Truth Oddity, merely known by a different name.
