Early Life
Tyra was born and raised on the planet of Gunzburg to Tor Miraborg and his wife. Her mother died while Tyra was still young, leaving her upbringing to her father. During this time the Free Rasalhague Republic was just emerging from independence from the Draconis Combine. With the Combine administrative structure gone, however, chaos ensued as people left and right attempted to fill the power vacuum with their own visions of utopia. Into the fray stepped Tor Miraborg, who returned order to Gunzburg and become its ruler as the "Iron Jarl". He did not come out on top unscathed, however. Tor was left scarred and crippled when the mercenary company Vincent's Vigilantes broke contract over technicalities. The people of Gunzburg held Tor up as a symbol of sacrifice for the good of the nation and became fanatical in their devotion to him, including taking up his perceived hatred of all mercenaries. And in the background Tyra witnessed it all. She wanted to make him proud by joining the Gunzburg Eagles, climbing to the rank of Kapten in its AeroSpace contingent. But she could only stand by helplessly as her father slipped deeper into bitterness and hatred, fueled by the feelings and impressions of his subjects.
 Love and Loss
Tyra's life would reach a turning point when elements of the Kell Hounds were marooned on Gunzberg while en route to the Periphery on a pirate hunting assignment. At this time she would meet Phelan Kell, son of Morgan Kell and a MechWarrior in the Kell Hounds. Though raised on anti-mercenary sentiment, Tyra fell for Phelan and Phelan did likewise. Their romance was short but intense, even leading Phelan to petition for a spot in the Kell Hounds for her. Most importantly Phelan showed her a life beyond the confines of Gunzberg, things that she had never and would never be able to do if she stayed. The presence of the mercenaries also seemed to bring out the worst in Tor Miraborg and showed Tyra the kind of man her father had become. Reluctantly Tyra refused Phelan's offer but petitioned for, and received, a transfer from the Gunzberg Eagles to the First Rasalhague Drakøns. She would leave her homeworld behind and serve as the Honor Guard for the Elected Prince of the Free Rasalhague Republic. Fate, however, would conspire to keep her away from her father and home forever.
 Clan Invasion
Tyra and the Flying Drakøns, the AeroSpace wing of the First Rasalhague Drakøns, were tasked with escorting the Rasalhague Minster of Defense on his tour of worlds bordering the Periphery when the Clans began their invasion. Tyra first saw action against Clan Ghost Bear when they attacked the world of Thule. The Drakøns managed to escape this initial encounter and were recalled to Rasalhague to aid in its defence. It would only be a matter of time before Clan Wolf forces appeared in orbit over Rasalhague to claim the world for themselves. Tyra only saw limited action in the battle, for the decision was made to evacuate the Elected Prince from Rasalhague, which necessitated the re-deployment of the Flying Drakøns to cover the Elected Prince's DropShip. Tyra would not get a chance to return to the fight on Rasalhague; low on fuel and hounded by Clan Wolf fighters, the Flying Drakøns would have to follow the Elected Prince out of the Rasalhague system to safety.
 Death and Glory Over Radstadt
The Elected Prince was to be taken to Radstadt, a provincial capital and an important world in its own right. However, numerous mechanical failures would delay arrival to the system; such was the delay that the Flying Drakøns had been listed as "Missing in Action" by the KungsArmé. Thus it was a severe shock to the Elected Prince and his entourage to see an entire Clan battlefleet over Radstadt once they manged to arrive. Clan Wolf had just taken Radstadt, marking the deepest incursion into Inner Sphere space yet seen by the Clans. A war council was called by ilKhan Leo Showers, who wanted to use the meeting as a means of censuring Clan Wolf and putting the spotlight back on his Smoke Jaguars. Thus the Clans met over Radstadt, forming a fleet of assault DropShips and smaller WarShips around the massive Clan Wolf flagship Dire Wolf. When the Elected Prince's JumpShip arrived, there were no questions as to what needed to be done: the Elected Prince must be protected at all cost. The Flying Drakøns were deployed to buy the Elected Prince time to escape, making several runs on the Dire Wolf without opposition; the Clanners were just as surprised by the appearance of the Elected Prince's JumpShip and had no time to deploy their fighters. The tables began to turn, however, as Clan fighters were finally deployed and began to push back the Drakøns. It was at this point that the Elected Prince's JumpShip managed to successfully jump out of the system. Knowing that their charge was finally safe, the Drakøns made one final attack. Many Drakøn fighters were badly damaged in this final push, Tyra's included. Instead of turning back, however, Tyra piloted her stricken Shilone on a collision course with the Dire Wolf. She had a moments peace before her fighter slammed into the weakest part of the massive WarShip: the bridge. Her action severely crippled the Dire Wolf, but had a more profound impact than simple material damage: she had also managed to kill ilKhan Showers. Without a leader, the Clans needed to pull back in order to elect a new ilKhan. Tyra's sacrifice brought the Inner Sphere a year-long lull in hostilities, enough time for them to adapt to new tactics, bring new weapon systems online, and rally their forces to present a more united front against the Clan threat.
Though most undoubtedly awarded the highest honors (posthumously) by the KungsArmé for her heroic and selfless action over Radstadt, perhaps the greatest testimony to her achievement are several lines in the Clan epic poem, The Remembrance:
