Age of the Five

Age of the Five is a fantasy trilogy by Trudi Canavan. The books in the series are Priestess of the White, Last of the Wilds and Voice of the Gods.

The series takes place in a continent named Ithania. The Northern Ithania worships five gods collectively known as the Five, the only survivors of a war of the gods. The five gods of the Southern Ithania are claimed to be false and this leads to eventual conflict.

The Five have chosen five humans as their representatives in the world. These five people are called the White and granted extraordinary powers by the gods. Auraya, the main character, is the last of the Five to be chosen. She tries to get adjusted to her new position, starting as a diplomat. During the series she discovers her innate magic is stronger than it was thought to be and goes forth unearthing secrets that have been resting for a very long time.

Tropes used in Age of the Five include:

The Ageless: The majority of the Wilds. The most extreme example is The Gull - the oldest of the Wilds, who has the physical body of a prepubescent child.
Call a Rabbit a Smeerp: The author renames everything to the point of needing a glossary in the back of each book. She justifies this in an interview by saying that coming across the word 'sheep' during a fantasy novel can kinda spoil things.
Cessation of Existence: What everyone believes happens with the Dreamweavers when they die, since they do not worship gods. It is revealed that the gods have no power over the souls of the dead or knowledge of what (if anything) comes after. They claim that they do so that they would always have worshipers to serve them.
Color-Coded Patrician: Ordinary priests' and priestesses' circs (kind of cloaks) are rimmed with blue. High Priests and Priestesses have rims of gold. The White... well, white.
Conflicting Loyalty: Auraya is torn between her duties as a White and her loyalty to the Siyee.
Divine Date: Auraya and Chaia
Everything's Better with Princesses: Imi is the daughter of the Elai King.
First Girl Wins: Auraya ends up with Leiard.
Functional Magic: spells are cast using a kind of background magic, that can be depleted from a certain place for some time.
God Guise: The Pentadrian faith is thought to be the high priests taking advantage of people, since everybody knows there are only five true gods and these are the Five. It is revealed that any human with sufficient magical ability could become a god and they are not special or worthy of worship
- It is further revealed that the Pentadrian gods are actually the Circlian gods in disguise, making this a double example.
Half-Identical Twins: The Twins (though it is implied that they used to be the same gender until one of them changed him/herself magically as a disguise).
The Heretic: Ellareen believes Auraya to be this.
I Am Who?: Leiard is Mirar, leader of the Dreamweavers, who is supposed to be long dead
Immortality Begins At Twenty: Both played straight and subverted. Most of the White and the Wilds are grown-ups when they stop aging, but the Gull is only a child. (Also Emerahl's innate ability is to change her age.)
Jerkass Gods: Both sets of gods in fact being as they are actually one and the same. They set up the entire war as a game to keep themselves amused.
May-December Romance: Auraya with both Leiard and Chaia
Memory Gambit: Mirar deliberately forgot everything about his identity in order to survive.
Never Grew Up: The Gull who is the oldest of the Wilds, but appears to be a child.
Older Than They Look: The White, who stop aging when chosen by the gods. Also the Wilds, who achieve immortality by themselves.
Our Angels Are Different: The Siyee. Descended from humans after a goddess decided to experiment. Their wings are more similar to those of bats than birds.
Our Mermaids Are Different: The Elai. Descended from human ancestors after a goddess decided to experiment. They are hairless and human-shaped. Lampshaded when an Elai sees a statue of a mermaid and is annoyed with its appearance.
Psychic Link: What the dreamweavers do when they gather.
The Reveal: Several. The more noteworthy are the gods' true nature and Leiard's identity.
Running Both Sides: Auraya eventually discovers that the Circlian Gods and the Pentadrian Gods are the same five. After the war of the Gods they set up two religions in isolation from each other then spent the next century building each one up in strength in order to finally pit them against each other in war (just for fun).
She's All Grown Up: Leiard discovers Auraya has done that.
Split Personality Merge: Happens eventually to Leiard/Mirar
Talking Animal: Mischief and the other veez, although their ability to talk is limited.
Inner Dialogue: Leiard/Mirar
Telepathy: Standard ability of most priests, especially the White.
Wizard Duel: Several between the Circlian and Pentadrian priests.
