I need Maglor endlessly following his big brother around, providing a running commentary to his life in lyrical verse, trying to cheer him up in the most obnoxious way possible. Like when they go out hunting or ride off to war, Maedhros was all grim and noble and purposeful, whereas Maglor faffed about and was determined to provide the sardonic yet spirited marching tunes. Preferably in true Monty Python style - lute in hand and no fucks given, while Maedhros fumed in the background:
Bravely bold Sir Maedhros, rode forth from Tirion,
He was not afraid to die, oh brave Sir Maedhros!
He was not at all afraid to be killed in nasty ways,
Brave, brave, brave, brave Sir Maedhros!
“Oh for Eru’s sake, Maglor, not again…”
He was not in the least bit scared to be mashed into a pulp,
Or to have his eyes gouged out, and his elbows broken;
To have his kneecaps split and his body burned away;
And his limbs all hacked and mangled, brave Sir Maedhros!
“Ahem, Maglor…I really don’t think that’s appropriate and-“
His head smashed in and his heart cut out
And his liver removed and his bowels unplugged
And his nostrils raped and his bottom burned off
And his pen-
*Maedhros lunges over and snatches away Maglor’s harp*
"I think… I think that’s enough music for today, Maglor."
