Voidknight Ascension 4

Though Sam's ascension to Paragon has elevated him to new heights, his overconfidence traps him in a trial on a dead world. Separated from his friends, Sam must survive the last Immortal Magus's training to navigate the Proving Grounds littered with mechanical monsters. The only way home is through. Sam will need to master a power he has barely begun to comprehend and venture into the Empire's war-torn past to return to a battlefield where new allies and old enemies await. Without his aid, more than just his skyshard will be destroyed by the all-consuming Maelstrom.
