Eris

She couldn't just leave a loved ally to their lonesome. She might take Phobos into the dreams of Dionysus, to birth wars, and fear, but it didn't compare to the company of the war god himself.
Even Enyo after a while gets bored, Eris asked her to come along too. "Maybe" was the answer.
Eris knew how it felt when Olympus excluded you. That wedding still stinks, even tho well avanged.

The next generation
She was the first whose body died. Ares was stuck, he didn't feel the wrath of time go over his head, she did. She came back, of course. A god like her couldn't really die like that. She and the others' bodies aged, not the gods themselves. Returning to their vessels from before, only to go back to the pride of the war god once again, with news of what they saw on Olympus.

Made you feel safe - story 3
She needed to get that spear out. She has to help, and find where that hunter is. It wasn't Artemis, or Apollo she was sure. The spear hurt, and seeing Deimos to similiar fate she went and protectively got ahead of him. She was much older that the twins, even if ten times more childish, those two were some of her only friends. Phobos rushed at the archer. From his spot, the huntress was clearly visible. They were only human. With that the two olympian already began their fight, but it only lasted a few minutes as Athena backed off, satisfied at the fight she gave the lion turned god. The god of war, retreated as the goddess went away. Pursuing wasn't an option for him; a son and a friend needed to be tended to.
Phobos and Ares helped the two other back to the rest of the pride for tender treatment. He was releived that the boy will be fine very soon, but that didn't meant his worries were all gone. Eris laid on the ground hurting leg streched out. He bumped his head to hears giving a gentle look. She adored him, as much as he was fierce and bloodthirsty in battle, he was as gentle, and protective of those he cared about. He could make her feel safe any day.
