There are two Archetypes to choose from once you unlock your Kheldian slot by achieving level 50 with any character. The first of these are Peacebringers, which are “Natural” Kheldians who have merged with human beings.

The other Archetype is the Warshade, which represents the fusion of a human with a Kheldian who has undergone radical scientific experiments to become a Nictus, a being of pure darkness. Though most Nictus feed on the life forces of others, the Warshades have seen the error of their ways and wish to redeem themselves by acting as legitimate heroes in the fight against their dark brethren. Peacebringers use any Enhancement a Natural Hero can, while Warshades can use the same Enhancements as Science Heroes.
