The song went:
- The guns are hot, the hull is ringing,
- The engines sing the sound of triumph;
- And every one aboard awaits
- A prize upon the high horizon.
- Hand and weapon! Heart and power!
- Cry it with the voice of Empire!
- Victory and prize and plunder!
- Vengeance flies at morning!
The residents of House Gensa sang "The Vengeance Flies at Morning" to Vrenn as he departed to become Thought Admiral Kethas epetai-Khemara's adopted son in the late 2220s. Although "Undefeated" was the House's song, Vrenn was a fan of Battlecruiser Vengeance. (TOS novel: The Final Reflection).
