Shadowhunters are sometimes called Nephilim. Easily identified with the runes on their skin that look like tattoos. Chester...her other name is Sere, right? She's shown me around a bit since I got here.
I'm a Shadowhunter so I help my sister and best friend hunt down demons that make a mess on Earth. Downworlders too if they cause a problem to munda normal humans. Humans often don't see what goes on thanks to glamours.
I'll let you see me though when we're walking around.
