Tethra’maan was a killer. That much is absolute. She fought with the armies, ended the lives of those who would use the powers of the daedra to harm others, and kept the general peace by whatever means necessary. If that meant calmly talking down a resident of the Shivering Isles, arresting them, or even ending their life, then it was done in the most peaceful way possible. But sometimes one’s options are limited, and the death of one could prevent the death of others.
Tethra’maan was no stranger to death. She watched as the Aureal and the Mazken threw themselves on blades, sacrificed themselves, did whatever was necessary to protect her and the rest of the residents of the Shivering Isles. But death was meaningless to the daedroth, and thus meaningless to Teth. She couldn’t die; not in the traditional sense. Sure, she tried to avoid injury and pain, but in the heat of battle, she did not feel a lick of fear for her own death.
Which is why dealing with death on Mundus felt so... weird. These people, these mortals, they live their lives so desperately afraid of death. Some did everything in their power to protect themselves; they lived boring lives in the safety of their towns and threw caution to the wind. Some tried to get the most out of their lives, aware that death was eventually inevitable, and threw themselves into danger at every possible moment.
The first time Teth was affected by the death of a mortal was when she was dealing with that attempted murder in Markarth, and after uncovering a city wide conspiracy, the man she was working with, Eltrys, was murdered. He had a wife and a child on the way, and was just trying to figure out what was going on and maybe uncover the reason for his father’s death, and he was killed for it. He had so much left to live for, so much to do in the short time he was allotted to live as a mortal, and it was pointless taken away from him. This wasn’t the kind of chaos that her mother would have wanted, nor was this the kind of order she tried to maintain. This was wrong, and Eltrys shouldn’t have died. Teth couldn’t attack any of the guards after she escaped Cidhna Mine (not without herself getting in trouble), but if she smirked as she watched one of the Forsworn impale some nameless guard on his blade, then so be it. And if she left a hefty sum of gold for Rhiada, then she’d say it was to do a good deed, and not to absolve any guilt she had over getting Rhiada’s husband killed. Tethra’maan did not feel guilt for mortals.
The second time was the death of Archmage Savos Aren. While confronting Ancanno, he put all of his magicka into a barrier to protect Teth, leaving himself unprotected from the blast. It was a waste, really. It wasn’t like Teth could actually die. Had Aren been one of the Aureal or Mazken, it wouldn’t really have affected her; she would often throw one of them as a conjuration into a pit of enemies to have them deal with it instead of her. But he was unique. Important. Mortal. There was no coming back from this death, no quick and easy replacement that would fill his place in the world. And why had he done it? To him, she wasn’t Tethra’maan: demiprince, child of Sheogorath and Akatosh, dragonborn of legend. She was just Tethra: student at the College of Winterhold. And only knowing that, he willingly sacrificed himself to save her. Why?
The third time was when she told Val that Marcus had been kidnapped by the Thalmor, and in exchange for not killing Marcus, Val had to go to the Thalmor prison and let Aerandil kill him. She told him it was bullshit, and that she’d go up there and kill them all and free Marcus herself, but Val refused. He wouldn’t let her leave without him, going as far as to follow her when she tried to leave. Why would he do that? She was more than capable of handling them herself, though she could understand why he might not think so. But even as a hardened soldier, Val was mortal. Human. Squishy. A blade in the right spot and they just stopped working. Val knew he was going to die if he went, and still did. Teth watched as Val’s paralyzed body fell to the ground, and took a sickening satisfaction in watching Aerandil’s face melt under the heat of her flames, as well as those of all his soldiers. But she was too late to save him. She felt the strangest emotion fill her as she listened to him beg Marcus to let him go, to him say that he could see his wife and children again. Regret? Despair? Loss? It was just another pointless death in the end.
What was happening to her, she should think. Was this a result of her time in Mundus? Were her body and mind being changed to be more... mortal? Her father had said that as she spent more time in this plane, that she would change the world and that the world would change her. She had thought that meant that as her body grew accustomed to this plane, and eventually regain her demiprince powers (good), become more like that of a mortal (bad), or some mix of the two (ehhh???). Surely, that was why she was reacting like such a.... mortal. This plane had done things to her. It certainly wasn’t that these deaths had slowly affected her and made her grow fond of these tiny, puny mortals. Not at all.
