Off-topic, but I floated an idea at JMG's Magic Monday to change the reference to "Sumarbrandr" in the HLBRP to "the Sword of Frey" or "Frey's sword" (long and short versions) to remove what I've learned is a reference to a modern Rick Riordan novel.

I plan to only change that part to start with, to see how it goes, but after that I'd like to try changing the wording of the other items to explicitly mention the gods best known for owning them: "Before me, Odin's spear. Behind me, Heimdall's horn. At my right hand, Frey's sword. At my left hand, Balder's ring." Something about that formulation seems promising.
