Due to this discovery, Doom lost all of his faith in the king and the royal family of Deltora and thus began his lifetime of bitterness and belief that the city of Del's people could only depend on themselves in order to survive.
Doom later encounters the trio at a Resistance stronghold following their adventure on Dread Mountain, along with an injured Dain who had saved them from two Grade 1 Ols (shapeshifting servants of the Shadow Lord).
Upon his coronation as King and Jarred's departure from the palace, he did not play a great role in ruling Deltora as the most important decisions were made by his chief adviser, Prandine - a Shadow Lord plant.
Eventually, Ranesh escaped during a rival crew battle and made his way to Del, encountering Fardeep in the Valley of the Lost, but refusing to play his game because he valued freedom over riches.
When Jarred escaped the palace after falsely being accused of attempting to assassinate King Endon, Crian took him in after finding him passed out in front of the forge, and threw his clothes into the sea to trick the guards into thinking him dead.
After he has run out of spins, and Lief has noticed most of the people win wooden birds, or at most one or two coins, he attempts to keep Kree anyway, but in the struggle, the cloth falls off and his scam is uncovered, forcing him to flee.
Nevets has been useful in several occasions, such as protecting Josef from Ols and killing Grey Guards that threaten Steven, Lief, Barda and Jasmine, as well as helping to defeat Paff's black slime monster when it overwhelms the topaz dragon.
He became the leader of the remaining Jalis after being entrusted Glock's talisman (consisting mainly of little odds and ends that his ancestors had gathered as trophies, formerly including the mouth piece of the Pirran Pipe).
They somehow end up in the possession of Laughing Jack, who turns them into large black horses like the one he already has, and forces them to help the transformed Red Han pull his wagon while abusing them, including denying them food and water.
They also have a deep hatred towards the kings of Deltora for the fact that Ballum, their founder, was driven from his palace by deceit from Elstred's advisor Agra (a servant of the Shadow Lord) and so Lief and his friends are forced to take fake names for themselves to disguise themselves.
Although they are small, Wenn are capable of subduing large prey by means of a sound they produce by rubbing their lower legs (similar to crickets), which drives animals to the point of insanity.
Jasmine tells Lief and Barda in The Forests of Silence that Wenn feed on the scraps left behind by the Wennbar, but the Deltora Book of Monsters claims they are herbivores, eating only certain kinds of leaves.
Muddlets are bizarre, albeit rare, gentle, and highly valued, beasts of burden who supposedly exist in central Deltora, around the area near the City of Rats, which have been domesticated by the plains people for millennia.
In the fifth book of the first series, Dread Mountain, Lief, Barda and Jasmine encounter the remaining tribe of Kin at Dreaming Spring and save their only young, an energetic youngster named Prin from a pair of Grey Guards.
Once a human sorcerer from Dorne named Malverlain had a deep hatred for all things good with a belief that in life, the Shadow Lord encountered the four sisters whose song had a negative effect on him.
But was repelled by a spell cast by the Torans and unable to bribe an emerald dragon to serve him, the Shadow Lord came to Pirra where he recruited the residential thieves and monstrous beasts of the mountainside into his services.
Furious, the Shadow Lord withdrew and began concocting a series of plans by using Ols to infiltrate Del and manipulate the royal family for generations, sending his Ak-Babas and implanting his version of the four sisters and the Grey Tide in Deltora.
Once the preparations were completed, the Shadow Lord resumes his invasion while having the Ak-Baba take each of the belt's dislodged gems to a perilous and terrifying place that is home to a monstrous creature to serve as an obstacle to any who try to find them.
As planned, this set Lief on a quest to destroy the Four Sisters, which the Shadow Lord hoped would lead to his death or unleash the Grey Tide, likely to make Deltora a part of the Shadowlands.
Thaegan has 13 demonic children who are named in an uncanny rhyme in the giant's riddle: "Hot, Tot, Jin, Jod, Fie, Fly, Zan, Zod, Pik, Snik, Lun, Lod and the dreaded Ichabod".
Laughing Jack was told to stop the companions' quest, (he acted more like the Sister of the West's guardian than Doran the Dragonlover in Isle of the Dead), but failed, first when he encountered Steven at The Funnel (in the territory of the lapis lazuli) and then when he broke an oath he made in the past.
He was very superstitious, and after they were trapped on the ocean for days when Red Han wouldn't put out the Bone Point light in exchange for his daughter's safety, came to believe Verity was a witch after the birds fed her.
In both versions, it turned out that Gorl's body decayed a long time ago and it was his warped consciousness controlling the armor until the tree branch damaged it to the point that the suit could no longer hold him and thus ceased to be.
Offering protection to them from the Shadow Lord, unaware of the toad's relation to him, the Dread Gnomes become Gellick's slaves and caretakers, tending to his every need and feeding him flies in return for a bit of the venomous slime he excretes which they use in their poisonous arrows.
But when ordered by her frighten mother to send the newborn creature back into the sea, Enna decided to run away and be with the worm as she is tripped by a wave of water and fell into a cavity which became the Maze of the Beast.
Furthermore, Lief realizes the monster seeing the preservation of its lair is more important than food, carving out a fissure in the side of a wall that lead outside that forced Glus to ignore Barda and Jasmine as it quickly closes the hole instead of chasing after its prey.
As seen in Doom's case, this ploy was intended to render the seeker of the diamond too disillusioned with the Deltoran Royal Family to the point of ignoring their reward and lose all faith in Deltora's king.
When Lief reclaimed the real diamond, the Valley of the Lost and everyone within it became purified because they had been forgiven for their betrayal, the "disciples" became alive again and the Fardeep returns to his original form, revealing the nature of his role as Guardian.
A sorcerer (confirmed to be the Shadow Lord in Tales of Deltora) came sailing from far away, looking for lands to conquer, heard their songs and despised them because he hated all things beautiful and good.
The Sister of the South was described as a corrupt version of the seven great talismans in the Belt of Deltora, it was the same size and shape but gray in color and it inspired feelings of greed and sorrow in people nearby, including Lief himself though he was able to resist it.
