Just kidding. I was 147 percent sure it was going to be a MASSIVE deal. As i’ve said before, Trek fans are among the most savvy in the world, and since Damon and I humbly consider ourselves fans as well, all we had to do was look at each other to know that it was going to matter A LOT.

If you don’t, if won’t prevent you from entering this amazing world that’s been taken care of for over forty years by the fans.

There are no SPIDERMANNERS or PIRATERS, or SUPERMANNIES.
Trek belongs to all of us. I see canon much like the constitution. It is living document, but it has some principles that are inviolable.
