It can be a lot of fun! Anderson also wrote a story called "The Tale of Hauk" entirely in Anglo-Saxon-derived English which fits the Vikingish subject matter rather well. For my part, I sometimes try to write without words derived from origins outside of Old English, but it can be exhausting to do thoroughly. But I find it to be good practice for being more concrete in my writing - most of those fancy Latin and Greek words are for abstractions.

As for what you shared on the Norns, thank you for this! I'm greatly looking forward to the book.

Cheers,
Jeff
