The Heaven's Commencement Core was an ancient relic unearthed by the Northern Duke of the Elster Family in The Empire.
Although the idea of advancing technology through archaeology is quite criticized by many scholars on the Terra Continent, it has to be said that this is a fine tradition of post-apocalyptic civilization—don't like it, don't do it.
Not to mention, what the Northern Duke unearthed cannot be called technological advancement at all.
It was technological ascension!
[The most important part of the Heaven's Commencement Core is its energy core, a complete 'True Aether Furnace Core.']
Carlos remarked, [It's said to have been made in collaboration between the civilization of the previous epoch and the most ancient Dragon Kings, the sole True Aether Furnace of this world. Even the Aether Furnace Cores of True Dragons are not as complete... It's a 'Semi-Perpetual Machine' of the same specification as that of the Ancient Dragon Kings.]
