Beta Agni II was the inhabited second planet in the Beta Agni system. This system was located within Sector 30. This was the home of a Federation colony. Since its settlement, the colony had recorded no significant geological activity.
In 2366, the colony had a sudden tricyanate contamination of its water supply. The contamination was neutralized with hytritium supplied by a landing party from the USS Enterprise-D. The incident was later found out to be the work of Zibalian trader Kivas Fajo, as part of a scheme to capture the android Data. (TNG: "The Most Toys")
