Other than being gay lovers, hunters and this wierd heartlight stuff. As I was reading the comic I wasn't even able to keep track which one is which at some point. They feel extremaly random to me. It's some reverse Pantheon stuff where im unable to like or even care about the hosts. Can someone explain to where were they fleshed out? Maybe i missed something but for now i hope that Varus will gain full control and just erase them from existence.
##TeamVarus
Well, from what we know, they are members of an ancient order, dedicated to protect what was trapped in the temple (which is why they were fighthing there during the noxian invasion, and not within their village). They are lovers and most likely skilled archers. They are obviously Ionians, especially Kai who seeks balance, even while struggling to fight Varus. Valmar (the blond one) seems to be a bit more reckless and he possibly likes to fight more than his heartlight (which means soulmate, I believe).
That's what we know about them so far. I don't think Riot will make this go further, as they serve only as a backstory for Varus. To be honest, I like it that way, the story was short, it was very cute and you can really feel what was necessary : the strong bound they share that allows them to fight Varus and stop him to take over the body.
Edit : I would love if Kai and Valmar could win over Varus, I really liked their story!
The comics were basically just an introduction of how they released Varus from his tomb and ended up trapped within in him.
I think "heartlight" just means "lover, soulmate".
Anyways, they're just two gay lovers, one impulsive and passionate, the other more thoughtful and emotionally stable, who were hunters.

"Heartlight" is clearly just an endearing term for "soulmate." How anyone can find that confusing or "weird" is beyond me. And your inability to sympathize with them and even root for the darkin instead says more about you than the story. Go grab a Darkin.
Vaarus 
They are actually both closet Darkin. Their real names are Vaalmar and Kaai.
I really liked the story and hope they could win over the darkin. I think the body is Valmar's and the mind is Kai but Varus is over all the both most of the times. Really hope the story to continue and ends up Valmar and Kai wins over the darkin.
