Only A Monolith Remains

What was once, now is covered
Completely obscured by centuries and ruins
Stones released from lost spirits
Bleak images from past worlds
Only a monolith remains after the collapse
What was once, now is but soil
Harvested ancient symbols
Shifts in the grand evolution cycle
Only a monolith remains after the collapse
Decayed and Obscured
What was once feared
Will be once again feared
Until the ultra-progression
Mega-regression is the threat
