Location from Bastion by Phil Tucker
The legendary location that may contain the truth about everything — the Great Souls' history, Scorio's reincarnation cycle, and the Herdsmen's centuries-long manipulation.
The Lost Cube is Book 4's MacGuffin in the best sense — not a meaningless plot device but a genuine answer to questions the series has been asking for three books. What are the Great Souls? Why do they reincarnate? What did the Herdsmen build? What happened to Ettera? The Herdsmen siphoned power from the Silverines' suns to fuel it. The Archmagus may have orchestrated its discovery. Scorio's reincarnation point may be connected to it. Every thread in the series traces back to this location, and reaching it means confronting truths that the power structures of Bastion were built to suppress.
An archspire of ancient construction containing the Lost Cube — architecture that predates current Great Soul civilization and may predate humanity's arrival in Acherzua. Its design suggests a purpose beyond storage: it was built to power something, or to contain something, or both.
