We first set out to find Tiamat The Bat Queen we knew she would be the hardest to defeat . It is hard to resist her Goddess form but we will have to manage . She is the first out of the Four Chosen Ones , Tiamat , The Griever , The Stygian , And Silithia . They are all maidens of The Destroyer they bid in his doing to protect him in his tower . Tiamat in the Twilight Cathedral , Griever in Anvil's Ford , Stygian in The Ashlands , and Silithia in The Iron Canopy .
