With recent events, I'm starting to collate a list.

Confirmed:
Halashtu (Fire Giant) - Paragon of Nier
Leonydes val'Virdan - ex-Paragon of Nier
Elandre is the Paragon of Illiir.
Meliros is the Paragon of Belisarda
Ss’Koreth is the Paragon of Nayal

Suspected:
Matias - Paragon of Beltine
ul'Zheng Po - Paragon of Hurrian
Merik val'Cessari - Paragon of Lianni


Other:
Calmemnon - a really naughty boy
Sarkelios, the Emperor of Fire

Hello,

There seems to be some confusion here.

Sarkelios, the Emperor of Fire is NOT a paragon.

Halashtu is the Fire Giant Paragon of Nier.

Also, Calmemnon is not the Paragon of Illiir.

I believe:

Elandre is the Paragon of Illiir.

Meliros is the Paragon of Belisarda

Ss’Koreth is the Paragon of Nayal


I am not sure that Merric is a Paragon at all. Though he is clearly an epic psion.

I am not sure that Lianni is capable of having Paragons
