Early on into adulthood, Finn decided he would travel the world. He grew tired of sitting around the same place for so long, and wanted to see more of what the world had to offer. Despite this grand goal however, Finn isn't much of a talker and is in fact a man of very few words. He can speak perfectly fine, he just chooses to do so only when it's truly necessary. So travel the world he did, and in doing so, he learned a great deal about the different cultures of the world. He would join them in various celebrations and rituals, all with the open mind of someone wanting to absorb as much information as possible. He would even go so far as to spend enough time in these places to learn their local languages. Within a couple years, Finn knew several different entire languages, and engaged in much appreciation of the various cultures he discovered.

Realizing how much more there was to the world outside his own, Finn would continue his travels, until he came to a stop in a fairly busy city. At which point he discovered his funds had run out. Left with nowhere to stay, Finn continued exploring the city, until he found a large Arena like structure, and outside it, numerous fliers indicating that free lodging, food and other facilities were available to those willing to join the Arena in battle.

Finn never considered himself much of a fighter. In fact, he was quite against it. He thought to himself, and wondered how he could even fight without some kind of weapon. Until he realized he had just what he needed this whole time. Throughout all his travels, Finn always carried with him a sturdy Shillelagh. Hand crafted by an older relative long since passed, the very top of the walking stick contained a fairly large metal sphere. If swung properly, Finn figured he would have a fine weapon on his hands if treated with enough care.

Finn would join the Arena's second season, and the first official tournament. Where he would debut in a match against Cyrus, who was also debuting in that very same match. The two would fight to the bitter end, but Finn would come out on top. As luck would have it, Finn would go on from there to win the next 6 matches in a row, culminating in him becoming the Season 2 Champion in his debut season.

Afterward, Finn would team up with the young shinai master Tama, for the Season 3 Grand Ball Cup tournament. Where they would not fare nearly as well as Finn would in the prior season. Despite the losses and eventually elimination, Tama and Finn got along quite well and enjoyed being a team. Needing a new team for the Boss Gauntlet after Tama would become one of Haliberton's students, Finn would recruit Thuddeus, as well as the young rising star Kane. As Finn sought to hone the two's skills, while at the same time improving his own as they descend the Gauntlet.
