I intend to do National Novel Writing Month again this year. I am thinking of a story based in the “1632 Universe.” This is a long-established universe based on time-travel.
But I am also toying with putting the thing up on Amazon as a self-published book. Buyers could order a hard copy (print-on-demand) or an electronic edition for their Kindle book reader.
Presume I only mention names of characters and places in the 1632 universe, “Ever since Mike Stern told us to …” and so on, would I be OK in terms of copyright?
