In season 1 episode 5 of Loki, we see a species of birds. What are these birds and what is special about them?
The show's head of production design, Kasra Farahani, describes them as "Void creatures". No additional info is given about them other than that his original concept for the void was a lot weirder and more surreal. Somehow they survived the studio process.
"The big giant hands, they were... I don't have a clear story for that one. [Laughs.] That was really just a visual thing, because we were trying to find moments to infuse The Void with surrealism. So that was the point of the giant heads, and also of the little Void creatures that look like the little peacocks. Originally, at some point, I was proposing a far more Salvador Dali-esque, Dada-esque version of The Void, and it evolved over time. But those bird creatures and heads made it through from the Dada-esque version to the English moors version of The Void.
In an interview with Fandom Kate Herron, the director of Loki season 1, explained about the Void birds and their name as Narvas based on the name of show's head of production design, Kasra Farahani's daughter Narva.
I also love those little Void turkeys. They’re called Narvas, because Kasra pitched the idea of them, so we named them after his daughter, Narva. I love those little creatures.
