Malekith (Time of Legends: The Sundering #1)

Passed over to succeed as king, elf general Malekith is wracked by jealousy and bitterness. Under the pretence of rooting out the pernicious cult of pleasure that is corrupting elf society from within, Malekith plots his revenge. When he betrays Phoenix King Bel-Shanaar and attempts to seize power for himself, Malekith triggers a tragic sequence of events that plunges the realm of the elves into a civil war from which they will never recover.
Malekith begins the epic tale of the Sundering by Gav Thorpe, and continues the Time of Legends series.
