Cool, cool! And Hii btw. :) 

Ok, so ideas. Please point out any holes in it. 

Thinking twins. 
Shy female light bringer. 
Clergy type who already worshipped the light goddess before this all begun. 
Magic - healing, light barriers, summoning temporary creatures made of light. (corporeal light spirits)

Human male. Not blessed or taken by the dark
bit opposite his sister, more outspoken, very loyal and protective. 
he's a good fighter and a skilled artificer. and can scribe sigils (if that's even a skill). 
(As for artificer gadgets maybe things like wrist a crossbow, retractable blades, flashbang like explosions ect depending on the level of fantasy tech you will allow, maybe a clockwork creature)  

Thoughts, feelings, limits, ideas? Any of that too similar to an existing character?
