When you entered The Temple of Eterra, the voice of the Epoch called out soundlessly. The Shard is close, and it pulled at the pieces you carried to become whole again.
You explored the depths of the ruined Temple of Eterra, following the soundless voice. Eventually, you found the Epoch's chamber only to be attacked by a flood of Void lead by the Emperor's Remains. Defeating the Emperor's Remains only slowed the Void, it continued to pour into the room until the Shards pushed back the darkness with a brilliant light and brought you to The End of Time. Here, you spoke with Elder Gaspar and learned that this place is an inevitable endpoint for all timelines beset by the Void.
