- This article is about the Archon of the Lyran Commonwealth, 3007-3039. For the later Archon who adopted her name, see Katherine Steiner-Davion.
Katrina Steiner (2976 – 4 January, 3040, aged 64 years) ruled the Lyran Commonwealth. Her reign is noted for the Peace Proposal that she circulated, which led to the Federated-Commonwealth Accords and the eventual creation of the Federated Commonwealth. Katrina was born on on the world of Gallery. She is the first daughter of Lisa Steiner and General Alexandr Weldon. She is older sister to General Nondi Steiner.
 Early Life
A sickly child, Katrina Steiner surprised her doctors by going on to pilot a BattleMech at the tender age of 12. Graduating from the Nagelring Academy in 2994 at just 18, she was posted to the 3rd Arcturan Lancers conventional regiment as an infantry officer and later went through various postings in different military branches. Her stated reason for this was to become well acquainted with all of them. Despite her meandering career path, by 3004 she had risen to the rank of Hauptmann-General. She commanded the 10th Lyran Guards (which is traditionally led by the Archon's heir, or at least member of House Steiner) and the 2nd Royal Guards before being promoted to the Strategy and Tactics Division.
 Marriage and Children
Katrina married her long-time friend and lover Arthur Luvon, the Duke of Donegal, in 3009. The following year saw the birth of their only child, Melissa. That was also the same year that Arthur died of cancer.
In 3020, Archon Katrina hoped to bring about a diplomatic solution to the Succession Wars. This peace proposal was rejected by all the Successor States, but marked a beginning of a cordial relationship with First Prince Hanse Davion and the Federated Suns. By 3022, Katrina and Hanse had signed an alliance treaty between their respective nations and the Archon had willingly betrothed her daughter, Melissa, to the First Prince.
