Ok so Lewis is a Tieflings,(yes I like dnd and yes this is a dnd storyline) that has and will appear in ellowyn story, he is one of ellowyn closest friends and one of ellowyn weakness, he isn’t shown as much in story due to 2 event that Lewis, ellowyn and a bunch of ellowyn old childhood friends were involved in, and a event that ellowyn was in as well Lewis that effect their own personal relationship that still haunts them, so 100% of time they meet in private or not a lot due to Lewis own weakness that affects ellowyn journey or reverse. However Lewis is a character I’m sure a lot of people will see as a (logically) hero but also a villain (personally)
