A second trilogy written by MercedesLackey and James Mallory, the Enduring Flame Trilogy is set a thousand years after the events of ''TheObsidianTrilogy''. Kellen and Idalia are worshiped as religious figures, and High Magic is long gone. However, Tiercel Rolfot and his [[ChildhoodFriends friend Harrier Gillain]] embark on the adventure of their lives when Tiercel discovers he is a High Mage.

Meanwhile, in a far-off desert, a Wildmage named Bisochim comes to believe that the world is out of balance without darkness. He formulates plans to bring back the dark, against the wishes of his bonded dragon, Saravasse.

Key figures:

* Tiercel Rolfort: A member of Armethalieh's ''[[InsistentTerminology minor]]'' nobility, and a prospective student at Armethalieh University, he finds a book on High Magic and casts a spell that mysteriously causes him to fall seriously ill, driving the two boys to head out of Armethalieh to find a Wildmage to cure him. He later discovers that he is the first High Mage in almost a millennium, and [[spoiler:bonds with Ancaladar after the elderly Jermayan dies, in order to obtain a source of energy for his spell-casting.]]
* Harrier Gillain: Tiercel's friend since childhood and youngest son of the Harbormaster of Armethalieh, he accompanies Tiercel to seek a Wildmage to cure Tiercel, as well as to take care of Tiercel on the way. [[spoiler:He later discovers that he is a Knight-Mage, and learns swordplay under Macenor Telchi.]]
* Ancaladar: Having bonded with Jermayan for a millenium, Ancaladar joins Tiercel and Harrier after [[spoiler:Jermayan dies , Elven King Sandalon having performed a Great Spell to transfer his bond to Tiercel.]] He acts as a mentor to Tiercel, training him in the use of the High Magic throughout their journey.
* Bisochim: A Wildmage who lives in the Isvai, Bisochim bonds with a dragon named Saravasse after she is injured and he nurses her back to health. He believes that the Wild Magic is out of balance, with too much Light, and intends to summon an Elemental Spirit of Darkness, Ahairan, in order to bring Darkness back into the world to counterbalance the Light. It is Tiercel and Harrier's goal to stop him from doing so.
* Kareta: A unicorn who brings [[spoiler:Harrier's Books to him,]] and joins the party for a short while. Constantly snarky, and getting on Harrier's nerves, she nevertheless aids them through the Elven lands (by purifying water sources, for instance). [[spoiler:Revealed to be Shalkan's daughter.]]
* Macenor Telchi: A Selkan warrior whom the group rescues from near-death, he acts as TheObiWan to [[spoiler:Harrier, teaching him the Selkan dual-sword form of swordplay. Later dies during the siege of Tarnatha'Iteru.]]
* Shaiara: Leader of the Nalzindar tribe of the Isvai, she leads them to a long-abandoned city in order to [[spoiler:escape the other Isvaieni's purge of the Iteru cities. Later, she becomes Harrier's love interest.]]

!!This trilogy provides examples of:

* ApocalypseHow: Regional: By the end, a large part of the Isvai desert has been environmentally wrecked, with oases, plant-life and wildlife absent save in certain areas, and the String of Pearls has been completely depopulated, with some cities completely demolished. The Isvaieni themselves have been reduced in number by around 2/3rds through attrition, with a number of tribes completely wiped out. On the other hand, the rest of the world has been left untouched.
* TheAtoner: After learning how he had been deceived by Ahairan, [[spoiler:Bisochim]] becomes this.
* CallARabbitASmeerp: Among others, ''shotors'', ''limuns'', and ''kaffeyah'' stand in for camels, lemons, coffee. Generally, this is {{justified|Trope}} by TranslationConvention, as the viewpoint characters had no experience with them until well into their journey.
* CapitalLettersAreMagic: Everything related to High [[YeOldeButcheredeEnglishe Magick]], Wild Magic, and the Balance. Pages containing discussion of Magic can easily have more capital letters due to this trope than due to Sentences Start With Capital Letters.
* ChildhoodFriends: Tiercel and Harrier.
* ContinuityNod: Back in TheObsidianTrilogy, Kellen got Jermayan to magically build a bridge across the Angarussa river, with the hope that it could be demolished after it was no longer needed. Fast forward a thousand years later, and the bridge (now known as Kellen's Bridge) is still standing...
* FutureImperfect: 1000 years on, and just about every detail in the original trilogy seems to have been {{Flanderized}} or altered in some way. For example:
** Kellen is known as "The Poor Orphan Boy", who worked on the docks of Armethalieh as a slave and was exiled for breaking a crate of Elvenware.
** "The Blessed Saint" Idalia was enchanted into the form of a Silver Eagle, but by the Endarkened, not the Wild Magic, and Kellen used the Sword of Light (drawn from the Black Cairn) to turn her back. They also conveniently forget to mention [[spoiler:[[AndYourRewardIsInfancy her rebirth as an Elf]] after her HeroicSacrifice.]]
** Kellen and Idalia's mother was the Wildmage Queen of the High Reaches, and Jermayan was the King of the Elves, and bonded to Ancaladar "The Star-Crowned". (Ancaladar is particularly amused by the last claim.)
** Armethalieh was a Wildmage city, not a Highmage city, and apparently without any form of weather control, since Kellen was lying in the snow when he was cast out.
* {{Hellhound}}: The Black Dogs created by Ahairan seem to fill this trope.
* HeroicBSOD: Tiercel, [[spoiler:after Ancaladar's disappearance.]]
* HeroicSacrifice: The Firecrown informs Tiercel that one will be performed before Ahairan is reimprisoned. Tiercel spends an entire book preparing himself to do it. [[spoiler:It turns out to be Bisochim.]]
* PutOnABus: [[spoiler:Ancaladar, at the end of the second book. He doesn't return until the very end of the trilogy.]]
* RecursiveReality: Tiercel proposes that the worlds are each nested inside the other like a puzzle box. When "lined up" properly, something can move from one world to the other.
* TheUnpronounceable: In the final book, we find a ''tehukohiakhazarishtial''. This is a hollow mountain filled with molten rock, or as most English-speakers would say, a volcano.
* WellIntentionedExtremist: Bisochim considers himself this.
