This map region in my championship arena was a water region. An enemy team would have started here. This is the only region where I had the enemy that started here had already discovered the clue they needed to complete the quest. This forced the players to seek out this team and take the clue from them (either steal it or defeat the team). The idea was that the other team discovered a statue missing sections and they dug up the sections and returned them to the statue. For this, they got a cryptic set of instructions that explained the arena. You can see the lava region at the bottom and frozen region to the right. The center building is in the bottom right corner.
