Brotherhood of the Kalrei... need help...

Okay, this is one of my 'brick walls' in which i run into, in this case (although i have one or two ideas and that is it) I can't for the life of me find ideas for members for the group of killers in which i have created (link here: . I am stumped and so I ask for you're help... yes you and you could help me create a badass killer of a guild of reckoning. You could either comment on the journal and make sugestions or you could actually give me sketches if you would like to do that and if so there are a few i would like too make clear about specifics on the characters themselves:
1. They must have a mask, as due to their belief that it shows their loyalty to Medyous the archangel. Their clothing could totally be unique to them and their mask aswel but there's got to be a mask.
2. Their weapon of choice has got to be an axe, whether it be like an executioner's axe to a tomahawk axe.
3. They must have there own unique ability,nothing too small but nothing too god like (already have a plan for that), just a happy medium.
4. They are not only human members there are alien members too so aswel make up a new species for the character and give him/her a personalty.

Anyone who actually help me with this will be credited for their help and i will not be a thieving B*****d and claim it all as my own original ideas, i know how it feels.

Thank you to anyone who would like to help me and it may take a while to get the drawings done as i have things going on at the moment that i need to deal with. Again, thank you.
