The Bloodline of Zacariah

Walkthrough
Geomancer must be set as your main job to get the starting cutscene.
 * Speak to Sylvie in Western Adoulin for a cutscene.
 * Obtain 3 Acuex Ores and trade them to Sylvie.
 * Acuex Ore are obtained only as a drop from Putrid Acuex and Flatus Acuex in Cirdas Caverns (and can be purchased from the auction house).
 * Next, head to M-8/9 in Cirdas Caverns and examine the Overgrown Grave for another cutscene.
 * A Colonization Reive at M-8 may block the way and will need to be cleared to reach the grave.
 * Return to Eastern Adoulin and speak to Nhili Uvolep at I-7 for a cutscene and your reward.
 * You must wait one game day to begin the next quest.
