If I had to guess, they're just exceptionally skilled High Ordinators who Almalexia decided to make part of a special order, Her Hands. Special powers and enchanted armour, and poof, she's got herself some real nifty bodyguards.
Fat load of good they did her. Wonder what'll happen to them and their little group now that psycho lady's dead?
The answer is simple: they'll follow whoever is second in command in Mournholds Temple organisation, if he has enough influence over them without Almalexias protection. If not, other people will get rid of him and whoever's next in line with enough power and leadership skills will be made their "leader".
