I kinda figure out who's the one of the Absolute chosen.
"Ketheric Throm, the Absolute Chosen" around 39:25[video:youtube][/video]
it's a perfect fit for the description for one of the chosen
an armoured male elf, exuding power and command
and I might also dig out how things happened from the past to the present.
A bunch of people (include Halsin) tried to defeat Katheirc Thorm at the moonrise tower. Yet he managed to release the curse before being pushed out of the cliff and died(for which Halsin was likely responsible for that). Then the Absolute found his dead body, resurrected him and made him a Chosen. It kinda also explains why the cult of Absolute can survive in that area.
