Gamora and OTA (Multiples Welcome)
Gamora hadn't dressed up for the Halloween party because frankly, she hadn't known what Halloween was. It wasn't a holiday she'd ever celebrated, and it had only been curiosity that had her following all the strangely dressed people into the building.
As she looked around her, the strange thing to Gamora was that most everyone here appeared Terran. Sure, they were wearing differing costumes and so on, but under the makeup, they were just...humans. There was a strange homogeneity about it that struck her.
She would have turned around and left at once, but the food - apparently free and for the taking - caused her to stay. She went and took a glass of something and some sort of fruit, and leaned against the wall, trying to discern exactly what it was this celebration was all about.
If she had to guess, she would have said it had to do with Death, although she wasn't sure how death and dying earned their own party.
