Construction beginning/end

The Hyperion Federation builds their first ever Dyson sphere. This megastructure completely encases a star, capturing most of its energy. capturing immense amounts of energy for use. They have ascended to a new age, becoming a Type II Civilization. After thousands of years of being type I, now seemingly unlimited amounts of energy are made accessible by them. Forever a great beacon of their great history, even if they end up building a bunch of these things later, this one will remain special forever.
