Couples that were obviously gay but big time corp didn’t let it be cannon:
I mean come on
“ I learned that he had never married. I thought that odd, though I guessed why it was; No, I guessed that he wanted to remain "unattached” for some reason deep down which he did not understand himself - or would not acknowledge, for it alarmed him"
“Then the Havens were laid in ruin, and the tower of Barad Nimras cast down; and the most part of Círdan’s people were slain or enslaved. But some went aboard ship and escaped by sea; and among them was Ereinion Gil-galad, the son of Fingon, whom his father had sent to the Havens after the Dagor Bragollach. This remnant sailed with Círdan south to the Isle of Balar, and they made a refuge for all that could come thither; for they kept a foothold also at the Mouths of Sirion, and there many light and swift ships lay hid in the creeks and waters where the reeds were dense as a forest.”
“Last of all Húrin stood alone. Then he cast aside his shield, and wielded an axe two-handed; and it is sung that the axe smoked in the black blood of the troll-guard of Gothmog until it withered, and each time that he slew Húrin cried: ‘Aurë entuluva! Day shall come again!’ Seventy times he uttered that cry; but they took him at last alive, by the command of Morgoth, for the Orcs grappled him with their hands, which clung to him still though he hewed off their arms; and ever their numbers were renewed, until at last he fell buried beneath them. Then Gothmog bound him and dragged him to Angband with mockery.”
“At last Fingon stood alone with his guard dead about him; and he fought with Gothmog, until another Balrog came behind and cast a thong of fire about him. Then Gothmog hewed him with his black axe, and a white flame sprang up from the helm of Fingon as it was cloven. Thus fell the High King of the Noldor; and they beat him into the dust with their maces, and his banner, blue and silver, they trod into the mire of his blood.”
“Then Beren and Lúthien went through the Gate, and down the labyrinthine stairs; and together wrought the greatest deed that has been dared by Elves or Men. For they came to the seat of Morgoth in his nethermost hall that was upheld by horror, lit by fire, and filled with weapons of death and torment. There Beren slunk in wolf’s form beneath his throne; but Lúthien was stripped of her disguise by the will of Morgoth, and he bent his gaze upon her.”
“Thus he came alone to Angband’s gates, and he sounded his horn, and smote once more upon the brazen doors, and challenged Morgoth to come forth to single combat. And Morgoth came.”
“No cloud nor mist lay there, and looking down Lúthien saw far below, as a white light starting from a green jewel, the radiance of Gondolin the fair where Turgon dwelt.”
Headcanon about the dynamic between Mairon and Langon I talked about with @morelen. It´s kind of long so you can read it below the cut.
I imagine that Langon has been a servant of Melkor for longer than Mairon. Because of that Langon was trusted to be his mentor when Mairon first arrived in Utumno. He was not very happy about his new task of teaching this newbie. He had better things to do and was pretty standoffish and mean towards him. Mairon on the other hand admired him and saw him as kind of an older brother.
As Mairon quickly rose through the ranks Langon changed his attitude towards him and wasn’t so annoyed anymore. At this point when they are roughly at the same power level they work very well together. Mairon sees Langon as his equal, the both of them being Melkor’s most trusted servants. Langon on the other hand appreciates Mairon for getting Melkor off his back.
When over time Melkor starts to favor Mairon over Langon their relationship starts to flip. As Langon desperately tries to stay relevant he is depending more and more on Mairon talking favorably about him with Melkor who in turn is starting to lose interest in him. Mairon eventually notices how Langon is losing his footing and remembers how Langon used to be so arrogant. He decided to not hold him over the water anymore, taking the position of Melkor´s right hand man for himself alone.
Mairon got to travel around with Melkor and oversee the construction of Angband while Langon was pushed to the side. Though the moment when he finally fell deep and hard only came when the Valar knocked on the doors of Utumno and he wasn’t able to stop them from entering (this element basically follows the plot from “the chaining of Melko”, the fourth chapter of the book of lost tales part 1). While Mairon was able to hide in Angband Melkor was chained and taken away.
After this event Mairon was basically on top of the food chain, his only possible contestor still being Langon. But Langon at this point was known for his weakened position and for being the one who opened the gates to the Valar (even tho it was under Mekors command) and practically kicking off this devastating battle. As a consequence Mairon chased him out and moved the remaining forces westwards to Angband while Langon fled eastwards.
