-Fëanaro orders their host to move straight away along the Firth of Drengist (to move away from Losgar as quickly as possible without looking back.
-Maitimo rushes back to them, carrying a seemingly half-dead Telvo in complete panic.
-The brothers surround them, hoping to revive their baby brother with very little success.
-Fëanaro ends up carrying Telvo himself as he orders the host to move forward.
-For the first few days, after setting camp upon the waste of Lammoth, nearing the Echoing Hills of Ered Lòmin, Fëanaro keeps Telvo unconscious in his tent.
-He doesn't let anyone else enter, not even the frantic Maitimo and Makalaurë.
-Telvo briefly wakes up a couple of times, feverish and weak.
-The first time had been very brief, when he sees his father over him and asks if Pityo was nearby, only to remember that he was burned to death on the ships by Fëanáro and his brothers.
-Telvo panics and tries to get away, but Fëanaro holds him down, speaking to him in a half-fey tone and telling him that he was not allowed to leave him while still under Oath.
-The stress and fear of being trapped with Fëanáro causes Telvo pass out again, but the former holds him close and tries to reach out to him again.
-Eventually, a delirious Telvo manages to escape from Fëanáro's tent, calling out for his mother and brother, but ends up collapsing again in the presence of Maitimo.
-Realizing his mistake for letting Fëanaro take Telvo so soon after Losgar, after having heard Telvo's pleas while awake, he makes the firm decision of taking his youngest brother to his tent and keeps him there to take care of him.
-When Fëanaro realizes his youngest child was gone, he panics and searches, but soon learns that his youngest was now in Maitimo's care.
-He is against it at first, especially with all of his sons showing their reluctance in letting him by.
-In anger, he verbally lashes out at each of them and calls them disloyal, "like their mother and eldest brother."
-With more patience for his father than all the brothers at this point, Curufinwë is the one manages to finally convince Fëanaro to leave Ambarussa be.
-Over time, the brothers secretly visit their youngest brother while he is comatose and feverish for long periods of time.
-Maitimo stays at his side the longest, taking care of him while Makalaurë sneaks in to lull him to sleep, gradually healing his fëa with his voice.
-Whenever he is awake, however, Telvo will only allow Maitimo near him anymore, so the brothers sometimes guard the tent outside.
-They take care of him in little ways while too ashamed to face him whenever he wakes up, however brief each time is.
-Since he didn't have his twin to rely on strengthening his fëa anymore, they have to constantly and slowly nurture his spirit, hoping that it will eventually be enough, hoping that speaking to him and being close to him will give their baby brother the will to live again.
-They all worry that he will fade (since they don't yet know that the Oath prevents them).
-The burden of their Oaths weigh heavily on all of them.
-After almost a year has passed, the host is within Ered Lomin.
-Telvo has gained enough strength and spirit for his illness to pass.
-Though he still remains weak and depressed, changed since the death of Ambarto, everyone is relieved that he will live.
-The youngest son of Fëanaro no longer wants to be called by his father-name and mother-name.
-His father-name because he now wanted little to do with his father as possible, and his mother-name because he couldn't bear to use the name he shared with his beloved twin without feeling pain, and because the name often triggers Fëanaro's fiery rage whenever it is heard within proximity, or anything related to Pityo, so mentioning the name of his dead twin, or sometimes their mother, becomes a forbidden topic among them.
-Everyone (except Fëanaro, who still addresses him by his father-name) settle in calling him by his epessë, Atyarussa, though all his brothers miss calling him Ambarussa.
-Atyarussa starts to develop dark thoughts about his father. Every time he witnesses his father's madness again around the elves and speaks of the Silmarils, Aytarussa fantasizes about wishing his father dead.
-Neylo assures Atyarussa (though doesn't swear it) that he doesn't have to be anywhere near their father again.
-Over time, Makalaurë visits the tent every night to play some music like he would when Atyarussa was near-death.
-Unlike before, the youngest could no longer pretend that he didn't miss his second-oldest brother's presence, whom besides Maitimo had taken especially care of the twins as if they were his own.
-He doesn't say he forgives Makalaurë yet, but he lets the singer hold him close again and sing him lullabies as if he were a child again, sneaking memories of their time in Aman and happy memories of their family with the power of his voice.
-Maitimo continues to watch over Atyarussa and share the same tent as him, making sure he goes hunting again, trains with weapons, and even encourages him to assist the healers in camp to track down medicinal herbs (after listening to Tyelko, who used to be the one to do all those activities with the twins in the forests of Aman).
-Turko and Moryo were eventually allowed to join them on the hunts when circumstances demand it.
-Turkafinwë finds this opportunity also a good excuse to try reconciling with his littlest brother by doing what they both loved best.
-Morifinwë keeps his distance, but remains a shadow to his brothers.
-Like Curvo, Moryo blamed himself for Pityo's death, for being too eager to burn the ships in his own unstable wrath.
-Now harming his brothers in such a way, especially Atyarussa, becomes his greatest fear.
-Orcs attack them.
-After they the battle orcs and run them off, Moryo gets wounded while protecting Atyarussa, causing his youngest brother great worry at the time.
-With his medical knowledge, he manages to patch up Moryo.
-Moryo in his delirium apologizes to his youngest brother for "killing Pityo," shedding tears while saying it aloud.
-This causes Atyarussa to weep and embrace Moryo, and then Turko, both of whom wipe away his tears for the first time since leaving Aman.
-After almost losing Moryo, the experience makes Atyarussa realize that he doesn't want to lose any more of his brothers.
-Together, while scouting ahead, they are the first to find Lake Mithrim, which becomes the new settlement for the Fëanorians.
-For the sake of his family and people, especially for little Tyelperinquar (who had missed his youngest uncle), Atyarussa continues to live on and attempts to become a shadow of his former self in order to raise everyone's spirits, even with Ambarto's absence.
-Meanwhile, on days when his sanity finds some stability (which had been turning on-and-off since accidentally killing one of his twins, making him seem unpredictable and more feared than ever), Fëanaro subtly tries to steal moments to check on his youngest son when he either wasn't looking or when he was asleep.
-Ever since the burning ships in Losgar, though he never allowed Ambarto's name to be mentioned again, he still continues to blame himself for burning his other youngest to death in his darkest moment of madness.
-His grief and his obsession with the Silmarils keep clashing together, sapping away his body's strength and health, though he continues to hide it in order to appear mighty in the eyes of the Noldor.
-It was also due to secretly spending portions of his fiery fëa to nurture Atyarussa back when he was still ill and comatose.
-He sometimes sees illusions of Melkor and dead members of his family: Mìriel, Finwë, and a burned Pityafinwë standing separate from them, staring him with horror and accusation in the same way Telufinwë did.
-Faced with these demons, resenting himself for his unhealthy obsession with the Silmarils, Fëanaro becomes more determined and afraid than ever.
-He wants to protect his sons as much as possible from the Oath they made with him, in spite of his spiraling mental stability.
-Every time he tries to go to Atyarussa (especially during the times when he starts missing his wife), he is half the time stopped by the silent look his eldest son gives him whenever he is present.
-While Neylo will continue to serve when needed, he also never completely forgave his father for ordering the burning the ships––not only killing Pityo, but for preventing Findekanò, Nolofinwë, and the rest from following, potentially abandoning them to certain death on the ice.
-Fëanaro already realizes with great sadness that he lost the right to be a father.
-He feels the burden of the Oath he unwittingly brought upon himself like he never had before.
-Fëanaro realizes then that he had dragged all of his children into his Oath to hunt down the Silmarils because of his unhealthy obsession.
-His wrath towards Melkor, his desire for the Silmarils, and his fear for his sons' lives or desertion causes him to lose himself further to his feyness.
-With Melkor and his host so nearby, he wants to end the quest himself by defeating the enemy and reclaiming his Silmarils, which as a result will free his sons from their Oath without them having to get directly involved with his decisions anymore.
