The Darkins

This is more towards Riot, if any see this and hopefully answer. So I know with he has his abilites that are related to the 4 Horsemen of the Apocalypse. Well i was playing earlier ( one of my favorite champs) and came across a thought. He is the creator of war essentially and in his lore it talks about him being 1 of 5. i was more of wondering if you eventually you guys were going to come out with the rest of them and if some how they would have any similarities to the 4 Horsemen. being War of course. just a thought is all, not really sure how to ask Riot directly or i would instead. Thanks.
