In the early days of the Quebec City Citadelles, the main rival was Anchorage, as the two teams faced off in the playoffs what felt like every season including in a Four Star Cup final. But with the Armada's recent struggles for relevance and the natural churn of the J, QCC's rival has changed over time. I would argue right now that it is the Maine Timber or the Detroit Falcons. The Owls have had plenty of battles with those two sides in the postseason (including facing Detroit in one Four Star Cup final and Maine in two), and Maine has the added bonus of one of the closest teams geographically (along with Ottawa, who's too new to have any real beef with). In my opinion, the strongest rivalries are those that are born from competitive fire or geographical proximity, and since QCC is fairly isolated when it comes to the J it has to be forged in the flames of the battlefield.
