Erebus wasn't sure why he was there. Well, no. He knew why he was there. Nyx was there. And wherever Nyx went now, Erebus went too. That was just how it went. And she said they should go. So, he was there. It didn't help that both Eros and Melinoe had been taken. He was fond of both of them. They were why they were there, he assumed.
He followed Nyx into the warehouse, looking around as they made their way through the people there. There were more bodies than he expected there to be. He shouldn't have been too surprised. People didn't like when their loved ones were taken. He knew he sure didn't. Just the thought had him reaching out to let his fingers brush against Nyx. He didn't care where, he just needed to touch her.
He hung back, just listening to everything that was happening. Erebus was curious as to how they were planning to find and rescue the kidnapped gods.
