Final answer:
Skallagrim and Bera, characters from an Icelandic saga, are likely followers of the Old Norse religion, also known as Ásatrú. This could, however, change during the saga because of the shift to Christianity in Iceland.
Step-by-step explanation:
Skallagrim and Bera are characters from Icelandic sagas. Skallagrim is the patriarch of the saga Egils Saga, and Bera is his wife. The characters are typically presumed to follow the Old Norse religion, which is now known as Ásatrú. This religion honours the ancient Norse gods, such as Odin, Thor, and Freya. However, the sagas also cover the transition to Christianity in Iceland, and some characters, not necessarily Skallagrim and Bera, convert to the new faith.
