Earthy and flowery scents fill the air as you enter the final room. Something about this gym is...different. It's a massive greenhouse filled with various fungi and plants. A creek even runs through the middle. A man with unkempt brown hair wearing a green kimono stands at the opposite end of the room. Behind him towers an enormous tree with a gaping hole is in the trunk. Nothing but blackness can be seen inside. Its roots extend throughout the room.

"Welcome, challenger. Bet you didn't expect a druid to be a gym leader, eh? As you have probably learned on your travels, nature is both cruel and kind. A single tornado or earthquake can wipe out an entire city in moments, and the Earth Mother would think nothing of it. Yet the food we eat, even the very air we breathe, are gifts from her. You see, to truly be one with your Pokémon is to be one with nature."

The roots begin to tremble, as if they're...excited. Eager.

"So, trainer. Do you understand that you and your partners are part of the biosphere? Do you understand that we need nature, not the other way around? If not...you will never earn the Earth Badge."

The void in the giant tree trunk is suddenly filled with a single, gastly red eye that gazes down on you. Wait, is that...?

Let us begin.
