Falkstrom was the previous High Commander of the Ravenguard before Tadrith. He was serious, cunning, and determined, and had a great distaste of politics. He had very little tolerance for irresponsibility or laziness and while skilled in inspiring those under him, was also quite abrasive.
Through his efforts, he was able to keep Nevar safe from the Swarm for decades before leading a team of Ravenguard on a suicide mission into the Swarm Plane in order to close the Swarmgate permanently by summoning an eldritch being on the other side which consumed the gate and destroyed everything around it. He did this against the wishes of the Council of Magi, the Talons of Verdan, and Gavin Ashenwing when he was unable to tolerate continuing to risk even more raven lives in the name of political games over mana crystals, or pet projects – such as trying to befriend the Swarm.
Despite Falkstrom’s dislike of and conflicts with Gavin, he was portrayed by all sides after the closing of the Swarmgate as a selfless hero. This was done to honor his sacrifice (regardless of disagreements). However, it was also done to turn him from an influential figure not quite on their side into a hero that seemed to support the objectives of the new established government – something deemed needed in the midst of severe civil strife.
