The Secret Records of a Hidden Past

Far in the future, humanity still stands.
Advancing and adapting to the changes of time.
A glorious history of incredible progress with a minute amount of blemishes.
The people knew not of their true history.
They knew not what was hidden from them.
They knew not of the cataclysms of the hidden past.
Only a select few were worthy of this horrible knowledge.
Only the chosen understood the horrors of the hidden past.
Only this minute percentage of humans were allowed to admire the heroes of the dark past.
Among this lucky (or unlucky, depending on how one looks at it) few, one man was graced with the opportunity to experience this dark cluster of cataclysms.
A horrid task and a marvellous opportunity.
Failure brings annihilation and success brings glory.
