Giants are the monsters of human appearance but prodigious size and strength common in the mythology and legends of many different cultures. These big and tall creatures reside in the realm of Jötunheimr, and they are known as the Jötnar (Frost Giants). There are also other giants who reside in the realm of Muspelheim, and they are known as Eldjötnar (Fire Giants).
The Giants are an ancient race with longevity, like Gods and Dwarves. However in spite of this they are not very bright, and are rapacious eaters, particularly when it comes to meat and like Dwarves are no friends to the Gods.
Eggther was apparently the most fearsome of his people, gaining much reputation for his apparent brutality and killings, although he was soft at heart. Many Giants were killed for sport by Gods, particularly the thunder-god Thor, which made them dislike the more powerful deities. (Magical Fluffy Bunny World)
When a prophecy foretelling a time of great darkness for all Giants was told to come to pass with the reunion of Odin and Frigg, the Giants decided to send one of their own to kill the girl who would become the latter to prevent this from coming. They chose Bryn, since his abnormal small size would make him blend in with the mortals. However Bryn could not do the job once he laid eyes upon the girl, and vowed to protect her. He then told his people that he had killed her and sent them a possum heart as false evidence of his success.
However the Giants soon suspected they had been tricked, as all the signs indicated the girl was still alive. They tested the DNA of the possum heart, confirming their suspicions, and decided to send Eggther to finish the job and to punish Bryn. (Everything Starts With Gaia)
However when it came time to trade Gaia / Frigg for his hostage Zeb, Eggther gave up and allowed his soft side to take over when Zeb used reverse-Stockholm Syndrome, as well as the threat of Derrick / Thor, who nearly killed him. Axl Johnson / Odin promised that he and Gaia would not allow Giants to be killed for the fun of it by those such as Thor, and that their union would not bring about their prophecy. Eggther agreed to return home with this news, and warned Bryn that he could now consider himself banished from the Giant homeland. However before he left, Eggther warned Axl that his people had another prophecy where Jörmungandr was set to awaken. (Magical Fluffy Bunny World)
Subsequently their prophecy concerning Frigg would not come to fruition, as Gaia was possessed with the Spirit of Iðunn, not Frigg (Does This Look Like Asgard?) and it was discovered that Frigg had in actual fact already been reincarnated in Hanna Larson before the time of Gaia's ascension. (Late to the Point of Knowledge)
However it was discovered that the Giant's prophecy of Jörmungandr's stirring was true when Martin Larson / Heimdallr and Tigilau confirmed Jörmungandr was awakening. (Typical Auckland God, The Asparagus is Kicking In)
- Bryn's small size is referred to as a birth defect by other Giants, even his father and such is ridiculed often.
