You landed on the tower and now you have to get past those guards.
Look at the upper right tower wall to find a 1000 GILL COIN. Show the piece to the guards and bluff they did a lousy job searching you. They don’t see you as a threat anyway so you can go downstairs.
Trying to find Terra you must stop running round in circles. Use your knife on the bushes in the north to create a path. Then use the opening you’ve created to get through.
Walk to the left to meet with Terra.
