There are 2 possible meanings to this song 1 the speaker lives under the oppressive Abyss Lord so he tries to master the 5 Magics But the Abyss Lord already masterd the 5 Magics so the speaker fail and dies as derived from the line " He who lives by the sword Will surely also die".Or the speaker deafets the Abyss Lord but is corrupted by the power he now weilds and becomes the new Abyss Lord as derived from the line"He who lives in sin Will surely live the lie".Personally I prefer the latter.
