User blog comment:Death'sapprentice77/The Witch King Vs. Algol (God Match?)/@comment-121.216.213.45-20130322145049

Algol in his incomplete form is made up entirely of the energy from both swords. With this power he can change his size, weight, height, and teleport. The Tower Of Remembrance was materialized by Algol, one example of his power. The reason it decays and falls to rubble is because it's so hard to maintain with his power. Algol has no blood running through him, only energy. Can the Morgul blade really cause an affect on Algol?

Also, no human would be able to defeat him, those character endings aren't the true ending to the story, they just made it so Algol died to tie it all together.
