Wherever I wanted, as whimsy would ask, to do research and pursue enlightenment, to seek out creation and destruction, ultimate power and ultimate poverty, true love and absolute hatred.

To accumulate all of this knowledge, and return to humankind, and just... Give it to their brightest minds. Then tell them to explore the stars.

Then probably die.

Really the universe is a wondrous place and all, but if I had such a ship, I would use it for altruistic means to empower the rest of my kind to achieve a level akin to my own. Otherwise, I would be ever so alone, atop my golden throne. :hehe
