I've been thinking about Gimli and Legolas' relationship (couldn't tell you why) and how they spent the rest of their time on Middle Earth as companions, adventuring and whatnot. I'm not looking for anything specifically LoTR based, but I would love to explore the relationship between two men of different species and how their lives shift to accommodate and include one another, how they adjust to differences in physiology, aging, culture, priorities, etc. Just some good ol' fashioned romantic fantasy with plenty of world building, fluff, angst, and smut.
