Closest canon translations, preserving the plural explicitly, are qolasse and brendonne. Give the full sentence for context next time.

Edit: "Sword of Omens" can equally well be Zahkrii do _, Zahkriise_, or _zahkrii where _ is one of qolaas, qolasse, brendon, brendonne. Note that as a proper noun, this phrase takes the article faal and not fin.

it was in the context of "sword of omens" my friend asked me to translate a bunch of 90's cartoons into different conlangs and i chose dovahzul for thundercats
