This page consists of all the important minor characters within the Percy Jackson and Magnus Chase universes.

Baldur

Baldur (Old Norse: Baldr, Nordic: ᛒᚨᛚᛞᚢᚱ), also known as Baldur Odinson (Translation: Baldur, son of Odin), and also known as Balder, was the Norse @Aesir God of Light and Peace. He is a member of the Aesir Royal Family, being son of @Odin Borson and @Freya, paternal nephew of Vili and Vé, maternal nephew of @Freyr, younger half-brother of @Thor Odinson, and uncle of Magni, Modi and Thrúd.

At his birth, his mother learned from The Norns that he would die a "needless death". Determined to prevent his death at any cost, Freya at some point placed a spell on him that made him invulnerable to all threats, physical or magical. The spell had one weakness, however: mistletoe. To make sure no one figured out the spell's weakness, she cursed @Mimir to prevent him from speaking about it.

He was eventually killed by the trickster @Utgard-Loki, who manipulated Balder's blind twin brother Hod. His beloved wife Nanna would die of grief shortly thereafter.

Legacy

Freya mentions the story of her son to @Magnus Chase, @Mallory Keen and @Samirah al-Abbas on the train in Flåm, talking about her oversight and how she underestimated the Mistletoe in tiredness of extracting promise from various elements, species and gods. This proved to be very costly as it was the same plant that resulted in the death of Balder.

When @Thomas Jefferson Jr. is tasked by @Hel to find @Garm, the slain god Balder walks up to the son of Tyr to check if he is real or not. When asked if he could help him, he says he can not help T.J., but he does give him the arrow that killed him to immobilize the guard god. When Garm is back in his cave, Balder retrieves his arrow and leaves to wash it.

Diocletian

Diocletian was one of the last pagan Roman Emperors. He was a Roman demigod son of Jupiter (@Zeus), making him the last demigod to rule Rome. During his career, Diocletian became responsible for the deaths of several thousand Christians in his persecution of Christianity. Weakened by illness, Diocletian became the only Emperor to voluntarily abdicate the throne after his defeat at the hands of his nephew, Constantine, whom he had formerly exiled. He lived out his retirement in @Diocletian's Palace on the Dalmatian coast.

Legacy

After his death, Diocletian's ghost was said to haunt his the city of Split. His scepter held the power to reawaken dead Roman legionnaires. It could only be wielded by a child of Hades, and the spirits would only follow an officer of Rome. The scepter became a turning point in the second Giant War, when it was recovered by @Jason Grace and @Nico di Angelo.

After the scepter was retrieved by Jason and Greek demigod Nico di Angelo, the latter wielded it in the battle inside the @House of Hades. Jason was unable to lead the spirits, as he had just recently defected to @Camp Half-Blood. He stepped down as praetor and promoted centurion Frank Zhang to praetor. Frank led the legion of spirits to victory against @Gaea's forces, until a combination of demigods, Titans, and Gigantes worked to seal the @Doors of Death to prevent anymore enemies from escaping from the depths of @Tartarus.

Fafnir

Fafnir was a son of the dwarf king, Hreidmar. One day, @Aesir gods @Odin Borson, @Utgard-Loki and Hœnir (the god who helped Odin create humanity) were traveling when they came across an otter. Unknowingly to them, this otter was actually Ótr, the son of dwarf king Hreidmar, who had the ability to transform. @Utgard-Loki threw a stone at the otter killing Órt, and the three Aesir gods skinned the king's son. When they offered him to the king, he took them captive and forced @Utgard-Loki to gather ransom and fill the otter's skin with yellow gold and cover its outside with Red Gold. @Utgard-Loki did so by obtaining a net from Ran and capturing Andvari as a pike to gather his gold and ring named Andvaranaut despite being warned that he cursed it to bring death.

Loki didn't give the ring to Hreidmar to pay off the debt until a single whisker was left on the otter's fur. After the gods left, Ótr's brother, Fáfnir, killed his father to get all the gold for himself. He became very ill-natured and greedy, so he went out into the wilderness to keep his fortune, eventually turning into a dragon, which is a symbol of greed, to guard his treasure. Fáfnir also breathed poison into the land around him so no one would go near him and his treasure, wreaking terror in the hearts of the people.

Legacy

@Hearthstone Alderman told @Magnus Chase about Fafnir. After the ring was passed onto Sigurd, the curse of Andavari's ring was known as The Curse of Fafnir. Hearth's father, Alderman, was given the ring and began suffering the entire fate of Fafnir. The retelling of Fafnir finishes in this book. Alderman turns into a ring dragon, and Magnus, Hearthstone, and @Blitzen must kill him. Magnus (who "plays" the role of Sigurd) crawls into a Nisser hole directly underneath Alderman's cave. Heathstone uses Andiron's ghost to lure his father closer to Magnus so he can kill him. Alderman attacks his son and gets confronted by Blitzen, who gets him to back up far enough for Magnus to stab him. Later, Hearthstone is roasting the heart to eat it, and asks Magnus to turn the spit for him. Magnus gets overexcited and the heart falls in the fire, after he tried to catch it. He stuck his fingers in his mouth and gained the ability to understand forest animals just like Sigurd.

Mithras

Mithras was a Persian god who was adopted by the Romans with origins of the Mithraic religion being in Rome.

Mithras was the god of Roman warriors, the legion, and empire. He had a secret cult of warriors and was popular in the legions. He was one of the gods who replaced @Athena as a war deity. He was originally a Persian god before being adopted by the Romans. He was born from the rock, where he emerged fully grown and holding his dagger and torch. He was famous for slaying a sacred bull. Mithras' symbols are the torch and dagger, which one can be initiated into the cult with.

There are seven rites of passage to gain entrance into the cult of Mithras. There are also seven levels of membership, the top level being the pater, who @Annabeth Chase meets. If a person is an unbeliever, then they must die by fire or dagger.

Legacy

Mithras was again referred to when @Apollo remembered the type of monster protecting Nero's Fasces and remembered it to be the leontocephaline. Mithras was stated by Apollo to have been incredibly secretive that during his time in @Olympus as a Roman God, He, Jupiter and the other @Olympians barely knew anything about him. @Luguselwa mentions that while a lot of Roman officers worshipped Mithras back in the day, she had never taken to the Persian gods. Lu calls Mithras' cult an elite members-only society of which the emperor was an automatic member, explaining how Nero had found the leontocephaline in the first place.

Ymir

Ymir was one of the first @Jotunn to emerge into existence. Ymir was one of three beings to emerge from the primordial void, Ginnungagap (he is preceded by @Surtr, the primordial Fire Giant that melted @Niflheim's ice and instigated Ymir's birth, and followed by Audhumbla, the primordial aurochs that nourished Ymir with her milk), and the first Ice Jotunn.

His children, born from the sweat in his armpits and feet, ruled Niflheim the World of Ice. Ymir was finally slain by @Odin Borson (whose grandfather, Buri, was born from Audhumbla licking ice) and his brothers, and his body was used to form Midgard the World of Humans. Ymir's flesh became the earth, his blood – the sea, his bones – the mountains, and his teeth – rocks and cliffs. Finally, Ymir's skull became the sky, protecting Midgard from above. The maggots that chewed through his decaying flesh evolved into the first @Dwarfs.
