Oh, I liked this a lot! I love to think about the politics of who was placed where on that map of Beleriand and this does it well. I also like to think about the ways in which Maedhros interacted with his brothers. I think it answers the fanon cliché well. The almost forgotten pranks were hilarious and very nicely balanced against the ending where Maedhros reveals what I believe he truly must have felt.

"Of course I'm trying to protect you; you've not even turned one hundred yet! I'd put all my younger brothers in the south were it feasible, but it's not; as it is, I can hardly be faulted for doing what I can to ensure my baby brothers get at least a brief chance to enjoy their young adulthood before the burdens of war descend on us all. Don't be so eager to grow up, Ambarussa; it's a highly over-rated experience."

The beginning of the letter to Fingolfin is a perfect ending also.

Oh what a wonderful take and I am delighted to see what you did with this challenge. It reads so smoothly - to me - after Devious Council and the energy of the twins (Fëanorian energy doubled) just sparkles of the screen here. I hope those two enjoy growing up a tad more in peace with the youthful silvans :)

... pair of rambunctious young Elves who once filled all the fountains in Grandfather's garden with frogs and salamanders right before his spring festival party, which was made rather… memorable… by their presence, since they kept hopping into people's plates and croaked so loudly the musicians were all but drowned out.

 Oh this made me giggle so madly to imagine how the courtiers must have been shocked, or dismayed during this incidents: no music to be heard that also must have meant no political discourse at the tables.  Wonderfully written!

Copy of my MEFA review:

Ithilwen has managed to turn one of the drier passages in the Silmarillion (which itself reads a bit like a geography lesson) into a moving story. What I like about this story is the way it manages to combine the subject of politics with insight into the relationships between family members. Maedhros's lesson in map-reading is very convincing in itself, showing his insight into political aims, necessary compromises and strategy, while, at the same time, it conceals his ulterior motives with regard to his brothers. If his arguments were any less lucid, they would presumably not serve to convince Amrod and Amras. For Amrod and Amras themselves are clearly not easily satisfied - Ithilwen has certainly met the terms of the Fanon Inverted challenge she set herself by making them much more responsible and strongly motivated than they are usually depicted. Given the eventual outcome of Maedhros's plotting, all this is bitter-sweet. The mutual affection between the three brothers under challenging circumstances is confirmed and, in fact, Maedhros's calculations will more or less work out on both counts, as ensuing events in Beleriand go on to show, especially after the Dagor Bragollach - but, in the end, all this will still not be enough to save Amrod and Amras (or, of course, Maedhros himself).
