Battle of Crocus Field
The Third Sacred War (often just called 'the' Sacred War) broke out in 356 BC, and would present Philip with his first real opportunity to expand his influence into the affairs of central and southern Greece. The war was caused by the refusal of the Phocian Confederation to pay a fine imposed on them in 357 BC by the Amphictyonic League, a pan-Greek religious organisation which governed the most sacred site in Ancient Greece, the Temple of Apollo at Delphi. Behind the religious element, there probably lay a display of "realpolitik" in bringing charges against the Phocians, instigated by the Thebans. At this time, Thebes controlled a majority of the votes in the council, and at the autumn meeting in 357 BC, the Thebans were able to have both the Phocians (for the cultivation of the sacred land) and the Spartans (for occupying Thebes some 25 years previously) denounced and fined. Since the fines for both parties were "unjustifiably harsh", the Thebans probably expected neither party to pay, and thus to be able to declare a "sacred war" on either.

The "Prince of Nothing" trilogy was published between 2003 and 2006. It depicts the story of the Holy War launched by the Inrithi kingdoms against the heathen Fanim of the south to recover the holy city of Shimeh for the faithful. During the war, a man named Anasûrimbor Kellhus emerges from obscurity to become an exceptionally powerful and influential figure, and it is discovered that the Consult, an ancient alliance of forces united in their worship of the legendary No-God, a nihilistic force of destruction, are manipulating events to pave the way for the No-God's return to the mortal world, a Second Apocalypse to succeed the First.
