This one is Duma, the archangel of Silence (and silence of the grave). Mythologically speaking, he's Hebrew in origin and rebellious without actually falling with other archangels begging for God to give him another task instead of casting him out. They'd lost many in the war, after all. This version is specifically from the Sandman comics (DC/Vertigo). After Lucifer gives Dream/Morpheus the key to Hell and is like "fuck this shit, I'm out", all these gods are like "GIMME THAT KEY" and God was like "Naaah, that needs to stay with us" so he sent Remiel and Duma to collect it then sprang "lol you guys are gonna live there now" on them. Remiel's like "Fuck that shit." But Duma's all "*silent mkay and takes the key*" So now basically, he's the ruler of Hell.
He comes to Preya after *BIG SPOILER MOMENT* and is now questioning his dedication to his silence, the meaning of it, and how can he perhaps serve God differently. He's a brand new arrival but will be opening his own cafe in a bit here where silence, save for ambient noise, is magically enforced.
Initially, he will be communicating with emojis and gifs until someone convinces him that it's okay to write. Even monks who took vows of silence did it. Eventually, he'll break his vow but he needs a way to serve before then.
ADDITIONALLY, I bring you Glenda Chittock morta from Harry Potter. Not much is known about her in canon other than she's the hostess of Witching Hour on the Wizarding Wireless Network and is incredibly famous - to the point of having her face on a Chocolate Frog card. This particular version of Glenda is coming in just as she's getting into the job of hosting. 1980's sexism is getting her down and after a few violations, she hopped to Preya. She's been around for about a month, hosting radio here as well so anyone who listens to the main rock station will know her voice. In casual conversations, she's super Bristol but on the radio, she has a very sophisticated sounding accent to make sure she doesn't sound too trashy. ;P
