Darth, your hatred is not logical

The last Star Trek TV series just ended. The final Star Wars movie opens soon. Here's something that looks like the first meeting of the two universes:

"Mr. Spock had just returned from a business trip Beyond, to a planet called New Hope."

But it's not a crossover. The quotation comes from Jack Vance's novel Star King, first published in 1964. It's a classic sf revenge story, the first in the Demon Princes series. Read it you must.
