Before Seven Ancient Wonders Edit
Horus once belonged to Colonel Marshall Judah. When trying to make a point to his troops, Judah would beat her if she didn't do what she was trained properly. Jack didn't like his treatment of her, so when he left Coronado he stole her from Judah's office. Following this, he treated the falcon with loving kindness, which Horus reciprocated by being completely obedient and protective of Jack.
As Lily grew up, she was disappointed that Horus never played with the fake mice that she used to try and get her attention. However she learned upon throwing one at Jack that Horus, who snatched the fake mouse out of the air before it struck him, was loyal and protective of him. Max Epper told Lily that Horus obeyed Judah, her cruel master, out of fear, but because Jack was a kind master, she would die for him.
When the team was in Sudan looking for one of the pieces of the Golden Capstone, Horus flew above the team as they traversed the swamp, presumably to keep an eye out for enemies. When going through the tunnel, Jack kept Horus in a pouch on his chest, but for a short time handed her over to Lily while he checked one of the traps. As Jack was clamped to the floor, Horus grabbed a falling torch that would have ignited the oil around him.
During the chase involving the Halicarnassus and hostile forces, Horus snatched a gun from an Egyptian soldier to keep him from killing Jack and Sky Monster. But after Jack was captured, Horus was unable to follow, and returned to the team's old farm in Kenya. Soon Lachlan and Julius Adamson arrived, shortly followed by Jack and Pooh Bear.
Horus accompanied the team to the Second Vertex, but when Jack fell into the abyss to ensure the Pillar's placement, Horus followed him down, and Sea Ranger noted to the twins that they should let her as her destiny was linked with Jack's.
Fortunately Jack survived thanks to a Maghook, and noted her loyalty when she perched on his shoulder, as he began climbing out of the abyss.
When Jack decided to go to the Sixth Vertex on his own since the rest of his team was wounded, Horus was unhappily teethered to Sky Monster's arm to keep her from trying to follow.
Between The Five Greatest Warriors and The Four Legendary KingdomsEdit
After Jack, Zoe and Lily adopted a pair of dogs, Ash and Roxy, Horus tolerated their presence, but whenever she was harrassed by the latter (usually Roxy's attempts to get Horus to play) Horus would take the poodle's favourite toy and leave it on top of a bookshelf, to Jack's amusement.
- Horus's name is derived from the Egyptian deity, and the name itself is thought to mean falcon.
- Considering the longest known lifespan of a peregrine falcon in captivity is 25 years, and noting that Horus has been with Jack since 1990 when he rescued her from Judah, (and even then keeping in mind that she must have been at least a few years old in 1990) Horus has surpassed this expected lifespan.
- This makes Horus' assumed age to be somewhere between 27 to 30 years old (as at the 2016 setting for The Four Legendary Warriors, where it is briefly noted that Horus is an old bird).
