Your first faction.

I started playing Heroes back in 1999. It was the third game in the series, and I stumbled upon it purely by chance. If I hadn't, I might not be writing this now. I really enjoyed the game, and my first faction was Fortress. At first, I didn't have a preference, but eventually, I chose Towers. In 2004, I discovered the sequel, "Heroes 4," and played as Necropolis/Inferno. After that, I played other games until the release of Heroes 5, and I've been playing as Necropolis (especially) or Inferno ever since.
