Word Association is losing its appeal to me. So let's play "Star Trek Shiritori"!

Shiritori is a Japanese word game where one player says a word, and the next player says another word that begins with the same character that the previous word ended with. For this English version, the next word must start with the letter that the previous word ends with, AND all words must be terms used in Star Trek (from any series or movie in the franchise).

Rules:

1. Next term must start with the final letter of the previous term.
2. If you use a word that has been used before in the thread, you lose.
3. You may also use a two-word term as long as it is used often in Star Trek as a combined phrase (such as "warp drive").
