Belka (ベルカ Beruka) was the home world of the magical civilization Ancient Belka (古代ベルカ Kodai Beruka), the dominant force in the Nanoha multiverse before its fall and the rise of Mid-Childa. "Belka" can also refer to the combat-oriented magic system that was developed by their civilization.
Trivia
- Nanoha's Belka may have been inspired by the nation of Belka from Ace Combat 5: The Unsung War (2004) and Ace Combat Zero: The Belkan War (2006) video games. Fandom has since embraced the crossover idea with fan-made trailers.
