So. This is a slightly misremembered scene from a lotr fic I read-
By that I mean I reckon I got the chaos but it's not word for word, I just thought it was hilarious. The fic is called 'What the Hell is Happening???' by Leader_In_Red.
Characters here are: Glorfindel, Legolas and Maglor, along with our pov character, Hazel.
Maedhros is also in this scene, but I forgot to draw him till a bit too late and I could not be bothered reworking everything after I'd already finished colouring. Just know that he is somewhere sword in hand with an 'I am disappointed in you Maglor' stare.
I would highly recommend this fic you're a lotr fan btw, (it's got a lot of stuff from the silmarillion, but most of the stuff is explained in the endnotes for those of us *cough -me- *cough who do not remember what actually happens in the silmarillion/couldn't be bothered reading it)
Premise is 'young lady out for a holiday finds elf in backyard- oh wait there's more-'
(I'm paraphrasing, but I feel like that's as good a description as any)
