In the Lore, Freyr the twin of Freya sends his servant/ avatar to woo Gerda in a story widely interpreted as a metaphor of the warmth of spring bringing fertile green growth to the earth. In that story, Freyr gives up his sword for marriage. This is interpreted to mean he becomes a god of peace when he marries, which is why his temples forbade weapons inside. The Asatru wedding ceremony includes the transfer of the groom's sword to the bride, which may be an echo of this tale. In Voluspa, the Prophecy of the Seeress, Freyr is foretold to wield antlers instead of a sword at Ragnarok. Because of his, he is sometimes depicted as an antlered god.

In the Fireverse, Freyr and Loki don’t really get along that well after Freyr’s marriage. Fireverse-Gerda was an important witch in Jotunheim and had been being considered to take over the spot that Hel had originally been expected to fill before becoming queen of the world of the dead. (At first Angrbodha didn’t know if Hel was going to survive birth, since she sloughed half her skin almost immediately, but after it became clear she was going to live it was thought she might become the priestess of the hot well of the Iron Woods, the keeper of the source of the river that powered Jotunheim’s thermosynthetic ecosystem.) So Gerda becoming part of Asgard society kind of messed up some of Loki’s relatives plans, and Loki wasn’t convinced Gerda really wanted to be there and that ticked him off. That is plot-driven story stuff, though, so I don’t know if any of it applies outside the Fireverse.

Because the parts of Some Say Fire that are retellings of the Lore are told from Loki's perspective, told by Loki to the human character P, when Fireverse-Loki has a particular slant on things it can change how that part of the story is told. This is of course true any time a story is told by anyone. No doubt many things we think of as being part of heathen mythology were just how Snorri saw it.
