Throughout the production of a series, a lot goes on behind the scenes in regards to planning and design, which often go through multiple stages before resulting in the final version that is seen on screen. Some concepts and ideas can have an effect on the show and characters, and unexpected occurrences during production can also lead to changes and additions to the plans for the show.
Raven Branwen alludes to Huginn, a raven who flies around the world gathering information for Odin. Specifically, she alludes to the poem Grímnismál. This allusion has had the following influences on the character and show:
- Raven is named after the bird that Huginn is.
- In the scene in "Burning the Candle" where Yang Xiao Long tells Blake Belladonna about her search for Raven, lines from Grímnismál that talk about Huginn and Muninn are written across the top of the chalkboard.
- "Hugin and Munin fly each day over the spacious earth. I fear for Hugin, that he come not back, yet more anxious am I for Munin."
- Prior to the events of the series proper, Raven left her team behind. This connects with the line "I fear for Hugin, that he may not come back" in the poem.
- Raven's face was first seen in the Volume 2 after credits scene. Due to time constraints, she had Yang's hair model, and her face closely resembled Yang's with slight adjustments to the shape of her eyes. In her next physical appearance in Volume 4, she has her own model with distinct hair and eyes from Yang.
