When you sneak past the healer patrolling around the sanctum at the top end of town to exit off the top of the town's screen while Kraden accompanies you, you come across the Sol Entrance; press up against the double-doors to enter the dungeon and watch a brief cutscene. There are random monster battles here, but all of them are very weak and easy to deal with whether you use offensive Psynergy like Flare or not, and if you spend enough time fighting them to level up to 5 (not necessary, since there is no boss battle at the end), random battles will no longer trigger. The layout and puzzles of the dungeon itself, likewise, are extremely easy by the standards of the rest of the series and are meant to introduce the general dungeon-solving methodology players will be using in all future dung
