It follows the adventures of three companions, Lief, Barda, and Jasmine, as they journey across the magical land of Deltora to awaken the last seven dragons and destroy the Four Sisters (creations of the evil Shadow Lord, which have been poisoning Deltora's crops causing the people and creatures of the land to starve).
The novels in this series are Dragon's Nest, Shadowgate, Isle of the Dead, and The Sister of the South.
Proclaiming that he is a prince, he is taken into Lief's party out of pity and later on believed to have been killed by a ruby dragon, though this is false.
Also known as "Dragonfriend" by the dragons, Doran is Deltora's greatest explorer and was a kind and noble man.
Lief and his group managed to finally meet him and Doran was saddened to discover that the diamond dragon was dead, but was overcome with joy when he found out her daughter still lived.
Veritas, the amethyst dragon, was forced to destroy Doran by stealing his breath in order to destroy the Sister of the West that he guarded, but knowing that the diamond dragon species still lived and that there was still hope for Deltora, Doran died a peaceful death as he disintegrated into dust.
When Ranesh left to Tora, this young girl took his place as assistant librarian to Josef, but it is revealed she is a servant of The Shadow Lord and guardian of The Sister of the South.
These are a few of them: The four map pieces (East, North, West, and South) that were made by Doran the Dragonlover and helped Lief find the four sisters each had a fourth of a poem.
Sisters four with poisoned breath/ Bring to the land a long slow death.But death comes swiftly if you dare/ To find each sisters hidden lair.Their songs like secret rivers flow/ To hold the peril deep below.And if at last their voices cease/ The land will find a final peace.
[1]The companions thought that meant after they defeated all four Sisters the Shadow Lord might give up on trying to rule all of Deltora.
At the entrance to Dragon's Nest the stone inscription said: Travellers do not pass this way, all are doomed who disobey.Turn your faces to the west, death awaits in Dragon's Nest.At the entrance to Kirsten's castle the poem was: Do not enter this domain, flee this realm of fear and pain.Death and terror both await, those who enter Shadowgate.
[2]At the foot of the rock bridge on the Isle of the Dead the inscription said: If you pass your fate is sealed, ahead pure evil lies concealed.Turn while you have life and breath, flee this realm of living death.
