Tear Jerker / Fire Emblem: Mystery of the Emblem

• Elice says to your Avatar at one point that you should protect both Marth and his ideals because this world is too cruel for his beliefs. Then, in the game he has to make some pretty tough decisions.
• One of the first decisions Marth has to make is to kill General Lorenz. After all that time in previous games trying to protect him, you're now supposed to kill him. And it turns out that Lorenz is pretty damn innocent! And if you think you can get out of it by talking to him, nope, he dies anyway. (In fact, it's possible he commits suicide if you do this, though it's ambiguous.)
• Early on in the game, one person in a house says that someone takes people from villages. Especially the really pretty girls. Gross and sad.
• At one point, early on in the game, you'll come across a village with a girl named Marisha. An old lady there offers her up to you, a complete stranger, because the things back at home are so bad. Seriously! They're offering up people to random strangers just so they can get away from the imperial army!
• Est and Abel. They got married after the War of Shadows, and they wanted to retire and run a shop together, but fate had other plans. First, Est is kidnapped by pirates in Valentia and her sisters have to save her, then, during the War of Heroes, she gets captured again when Altea was attacked in Marth's absence, and she was used to force Abel to fight against Marth. When she returns, it's clear that two captures in a row have dealt a huge blow to her self-esteem. She's no longer that cheerful and hyper-active girl we know, she's now feels a like dead weight for Abel, and even feels unworthy to be his wife. After the war ends, poor little Est says goodbye to her husband and leaves the continent of Arkanea because she doesn't want to be a burden, and Abel departs to look for her. They both disappeared without a trace.
• The War of Heroes as a whole, especially everything involving Hardin. One of Marth's most trusted allies from Shadow Dragon betrays him, and then you later find out it wasn't completely willing: his depression was enabled and twisted until he was brainwashed by the Darksphere, which now contained Gharnef's soul, and only comes to his senses as he dies. Not to mention that he genuinely loved Nyna, but while she did think well of him, she was still in love with Camus, so both were stuck in a loveless political marriage... but his last words are apologizing to Nyna for all the horrible shit he put her through.
• Katarina's subplot is pretty tear-jerking in its own right. The poor girl was treated like an animal since her childhood, raised in an Orphanage of Love until the woman running it changed for the worse, and sent to infiltrate new recruits to try and kill Marth. Never did she imagine that she would find real friends with her fellow recruits and that she would grow to care for them, and then she had to betray them. When the Avatar faces her again and tries to convince her to stand down, she tries to convince them (and herself) that all that time together was a lie, and she finally breaks down in tears, even begging them to kill her for all she's done after the battle is over.
  • Special mention to Katarina's death quote if you decide to kill her:
    Katarina: Thank... you... ... Now I... won't have to hurt Avatar... anymore... Avatar... I'm... glad I could meet you... During those days of training... you showed me a beautiful, happy dream... Hey, Avatar... Today's training... is about to begin... Look, there's Prince Marth and the others... Don't... wait for me... ... ...
  • Also the deaths of Clarisse and Eremiya. Despite all the trouble they cause over the course of the story, the former has a Stay with Me Until I Die moment with Katarina, and the latter is revealed to have been Brainwashed and Crazy by Gharnef, who took advantage of her grief over the deaths of the orphans she cared for during the previous war to turn her into one of his minions. If that doesn't scream Alas, Poor Villain all over the place, nothing will.
• In the end, Nyna can't seem to let go of her feelings for Camus and suspects Sirius is Camus and seems to leave Archanea under Marth's care in an attempt to go find him and get away from her horrible former life... but in the end, it seems like Camus/Sirius might have chosen to stay with Tatiana, as he said that he has someone waiting for him. So even if she does find him again and confirms her suspicions, she would most likely would never really find happiness with him, as he has fallen in love with another woman and is desperately trying to get away from his terrible former life.
• In New Mystery, the Wolfguards are recruitable. Recruiting them one by one, however, reveal just how horrible they currently felt. They wanted so badly to believe that Hardin was just having a bad day, they have sworn loyalty to him and must stay loyal to him, but in the end, they had to face the fact that the old Hardin that they swore loyalty to is gone and the only way to honor him now is to kill him and put an end to his sufferings. Wolf had it the worst; even after doing the deed, he still couldn't get over Hardin's passing, and so he threw himself to battle after battle, hoping that he'll follow after Hardin soon.
• If you didn't keep Caeda alive, at the end of the game, Gotoh would remind Marth that his victory came with a great cost and he sympathized with the Prince's sorrow. Before all these happened, Marth was set to be married with childhood sweetheart, and he lost her just before they could initiate the marriage.
