Pokemon Fire Red

Carved from the mountain's base, the Pewter City Gym is a fortress-like structure of grey stone, marked by two towering Onix statues at its entrance. Inside, the cool air and high ceilings create a solemn atmosphere, with a jagged battlefield that shifts underfoot, surrounded by carvings of legendary Rock-type Pokémon and their champions. The Heartstone ritual tests challengers' resolve, while Gym Leader Brock, known as 'The Stone Sentinel,' embodies calm strength and wisdom. Trainee watchers observe from above, ready to defend their leader's honor.

A monolithic grey stone structure with no frills, featuring two weathered Onix statues at the entrance and an inscription above the heavy stone doors. Inside, the arena is rugged and uneven, illuminated by beams of sunlight filtering through rock slits, with walls adorned by ancient carvings and plaques.
