LDB has the soul of a dragon which are all pieces of Aka and some embodiments of the Time God in TES are more pronounced or powerful than others. From slaying multiple dragons and absorbing their souls, the splintered fragment within the Dragonborn grows larger, more powerful. But his actions as a person definitely line up with a Shezzarine, someone who defends the interests of mankind on a physical and spiritual level. The LDB opposes the Aldmeri Dominion who are subverting or demoralizing humanity. He opposes Alduin, a Nordic God whos lost his way and is devouring the souls of revered warriors in Sovgngarde. He commands the Thuum a practice of Tonal Architecture that the Nords place immense cultural emphasis on.
