Eunice Natasha is the vlogger featured in Artificial Iridescence. She also makes some very minor appearances in Sorority Rites as Myles's "hyperverbal chatmate," E.N. Eunice's recommendation of Dere Alpha to Myles is, almost word for word, identical to one of PewDiePie's ads for his own game, Tuber Simulator (as shown in the first 24 seconds of this video). This is likely a simple, non-canon easter egg, showing that the developer is a fan of PewDiePie.

This pop culture reference continues in her appearances in Artificial Iridescence, where she is featured as a vlogger on VidSir. The tone and format of her EuNews videos are very similar to those of PewDiePie's "PewNews" segments. Her brief coverage of a story about Ava and Tristan's work at AppSir leads Clint to discover his wife's affair with her boss.

Eunice seemed very interested in getting Myles to play Dere Alpha, to the point that ulterior motives could be suspected. She is very clearly associated with Venice, who once described Myles to her sorority in this way: "She's the one. Perfect for the ritual. Plus, she's already connected. The Family will be pleased." As part of The Sorority, Eunice is likely also associated with The Family.

Although her main video-sharing platform of choice seems to be VidSir, Eunice also has a YouTube channel. On it, among other things, you can view her re-uploaded memorial video she made for Venice back in July 2014. She also has a presence on Twitter, where she comments on, or outright parodies, popular memes (usually ones relevant to the AppSir narrative).
