I've seen a lot of things.

( some were wondrous. some were terrifying. some were dangerous. so, he'd definitely seen things that would haunt his nightmares until old age. he'd seen things that he'd remember during his waking hours until memory itself became a problem. )

The type of thing depends on the way. But, it's a rush to discover a new civilization or a new planet. It's good to broker peace. It's not so good to get into fights but I find I'm pretty good at that too.
