Nope, you haven’t missed anything. We have a word for “black,”
“kut,” and a word for “jade” (or a similar mineral found on Cardassia), “terafa,” but no word for “obsidian” –yet.
@tinsnip, I’m thinking something like “tuxkit,” to mimic the (I’m assuming) sharp breaking sound you get when making an obsidian stone edge. Plus you can just sound so menacing with the word.
Side note: “kairhailo” comes from the Cardassian Sourcebook (originally spelled as “cairhailo”), but interestingly enough, when naming specific orders, they drop the O. Both examples given in the book are for military orders, though, so it’s possible this is a military-only thing. For now, I’d say you can use either Kairhailo Tuxkit (kah-eer-hah-ee-loh tuhch-keet, with the ch being pronounced as “Bach” or “loch”; IPA: /
kʰɑiː hɑiː
loʊ
tʌx
kʰiːt) or Kairhail Tuxkit–whichever fits best with your worldbuilding!
