As of Blood Ties, it's confirmed that Lightforging makes you immortal. What does this mean for the Alliance/Stormwind/Humans in general being led by an immortal being?

After many years, Turalyon was infused with the Light by Xe'ra, granting him immortality; he became Lightforged

^Blood ^Ties, ^chapter ^4

Lightforging now grants immortality, without being tied to a tree or dragon blessings, just the power of the Light.

How does this change the playing field narratively in your eyes?
