The Fires of Heaven (abbreviated as tFoH or FoH by fans) is the fifth book in American author Robert Jordan's fantasy series The Wheel of Time. It's notable for being the first novel in the series to not involve an appearance by each of the three ta'veren from the Two Rivers, due to Perrin's absence. The Fires of Heaven consists of a prologue and 56 chapters.
Chasing the Shaido Aiel, who have crossed over the Spine of the World and are pillaging Cairhien, Rand al'Thor, the Dragon Reborn and the Car'a'carn, leads his Aiel over the Spine as well. The two Aiel armies meet in the Second Battle of Cairhien, which is by far the largest battle in the Westland since the time of Artur Hawkwing, 1000 years past. At the start of the battle, Mat Cauthon saves some troops from a Shaido ambush. Guiding these troops throughout the day, he wins numerous battles using the memories of past generals he received in The Shadow Rising. He personally kills the Shaido leader, Couladin, in battle, and the Shaido Aiel retreat in defeat.
Falsely believing Queen Morgase Trakand of Andor dead at the hands of the Forsaken Rahvin, who is masquerading as Lord Gaebril, an angry Rand prepares to Travel to Caemlyn with a small Aiel strike force. Before he can do so, Lanfear, learning that Rand slept with Aviendha, is furious with jealousy and attempts to kill them. Moiraine Damodred grabs Lanfear and both topple through a doorframe ter'angreal, killing herself and Lanfear.
