Hvitur was a moon-pale silver IceWing with arctic blue eyes, the first dragon to appear in the series, the first guardian seen, the first IceWing seen, and the first dragon to die in the series. He was killed by Burn when trying to deliver the SkyWing egg.
Kestrel was a large SkyWing with jewel-hard, rust-colored scales, orange-yellow eyes, and burn scars on her talons from her attempt to save her daughter, Peril. She was a former SkyWing soldier under Queen Scarlet before joining the Talons of Peace. Kestrel was later murdered by Blister and Morrowseer on an island in the Bay of a Thousand Scales. She was the most strict and sometimes the cruelest minder. She is the mother of Peril and Ember who was killed by Kestrel (deceased).
Webs is a blue-green SeaWing that stole Tsunami's egg from the Royal Hatchery and was forced to flee the Kingdom of the Sea. When Hvitur failed his job to get the SkyWing egg, Webs went to the Rainforest Kingdom to get a RainWing egg that turned out to be Glory. According to Tsunami in The Lost Heir, he was the kindest "but should have protected them better." He is still alive as of Darkness of Dragons and is the current history teacher at Jade Mountain Academy.
Dune was a pale gold, male, SandWing soldier with a missing foreleg and maimed wings, who fled to the Scorpion Den. He was wanted by Thorn for stealing an egg that she hid, which turned out to be Sunny and was brutally killed by Queen Scarlet upon her initial discovery of the dragonets of destiny.
Asha was a MudWing soldier and revealed to be Clay's aunt. She was caught in a battle between Blaze and Blister's forces while delivering Clay's egg to the Talons of Peace, and died of her wounds shortly after arriving.
The guardians were charged with the kidnapping, protection, upbringing, educating, and all around caring for the dragonets of destiny. They were located in a cave system under a mountain in the Sky Kingdom. Each of the guardians was from a different tribe who no longer paid allegiance to their queens but to the Talons of Peace and also to Morrowseer, the NightWing who had delivered the prophecy.
The dragonets at times held deep grudges towards their guardians for the strict lectures and confinement within the caves. Webs had been more gentle towards them, Dune rejected Glory but appeared indifferent to the rest, although he cared more for Sunny given her "disabilities". Kestrel was the most despised by the dragonets for her ferocity and bad temper, though this can be attributed to her past.
Clay's egg was purchased by Asha, his aunt, for at least two cows.
Tsunami's egg was stolen from the Royal Hatchery by Webs.
Glory's egg was stolen from the rainforest by Webs to replace the broken SkyWing egg and complete the prophecy.
The SkyWing's egg was stolen by Hvitur but was destroyed along with him, when Hvitur and the egg fell off a cliff.
Burn stabbed Hvitur with her tail barb and threw both Hvitur and the Skywing egg off a cliff to their death.
Asha died from her injuries after delivering Clay's egg to the cave.
Dune was killed by Ex-Queen Scarlet in the process of the dragonets' escape from the caves.
Kestrel was captured by Scarlet and scheduled to be put on trial and executed but was rescued by the dragonets and her daughter, Peril.
Kestrel was slashed in the throat, stabbed in the heart by Blister's poisonous barb, and thrown off a cliff outside of the SeaWing Summer Palace. She was later found dead by a SeaWing patrol.
Webs was poisoned by Blister's barb when the dragonets fled the Kingdom of the Sea. However, the dragonets found cactus juice from the brightsting cactus that was used to heal him. He is seen alive as the history teacher at Jade Mountain Academy as of Talons of Power.
