Players can enter the Cave of Origin in Pokemon Ruby version by following Steven and Wallace, who is the Gym leader of Sootopolis City. Access to the cave is granted upon arrival at the entrance of the cave and the two men give instructions to enter.
The Cave of Origin is located on the north end of Sootopolis City. It is said to be the cave where life begins. Wallace serves as the guard of the cave, as residents of Sootopolis are forbidden entry. The player will encounter the cave in the Rain Badge quest in Pokemon Ruby and Sapphire versions. In these game versions, gaining access to the cave can be somewhat tricky. The following steps will help players reach the cave from Route 126.
Step 1: Defeat Swimmer Brenda
Before proceeding to Route 126, the player should fly to Mossdeep to stock up on supplies of potions and heal any necessary Pokemon. Once the player arrives at Route 126, Max Repel must be activated to get to Swimmer Brenda quickly. After the trainer falls, the player must look for a dark ring circling the volcano.
Step 2: Dive into the Ring
Once the ring has been located, the player must dive into it and look for the entrance to Sootopolis City. The player must then enter and surface into the city.
Step 3: Proceed to the Gym
The player will find the Sootopolis Gym located on an island upon surfacing. However, no one will be outside and it will be impossible to enter the gym. Instead, the player must walk towards the left, climb the stairs, head towards the right and descend. The player will then encounter Steven who will introduce Wallace.
The Cave of Origin in Pokemon Ruby and Sapphire versions will be very dimly lit so it is advisable for the player to have a Pokemon that has already learned the Flash move.
