Dragon Quest V Help

I am up to the point where I am with Prince Harry and we are now grown up. We go to Harrys castle but cant get passed the guard on the inside or through the door to the right where Prince Harry was originally kidnapped through. What should I do next please?I played around and sussed it . The journey continues.

Sorry I got another problem, I am now at the part where I am suppose to help this old man collect this herb that only appears at night. However, I have no clue how to get there I have been walking in circles, tilting at every angle but I still did not see the glowing herb. The only thing I saw glowing is in the water, any idea how can I find it?

At the old man's house, go and view the globe. It shows the location of the herb. Then just go to that specific location at night, and you will find it.

haha yea solve it yesterday, I kept thinking it was in town but it's actually outside =.=;;;

Prolly being retarded .. but where did everyone go? I came back with the water ring and everyone in the mansion is gone. It's not a bug right? Going nuts .. can't figure it out.

You need the fire ring as well.

I gave him the fire ring already .. then he told me to go fetch the water ring. I came back and only the sister is in the house .. telling me "what you think you doing, bringing this peasant girl into my room'. Do I need to do something after returning with the water ring in order for them to be in the house again? where could they have gone? I spoke with everyone in town .. they all taking about the wedding.

Once you've got both, head into the Mansion. That's all I did, and then I talked with the father.

hmmm .. hear about a save bug at that town.. i saved before heading back to mansion .. tell me I ran into a bug and need to restart and I'd be upset :( Nobody there .. only the maid - who moves out of ur way when u enter and the other daughter at top floor. Is he suppose to be in the same room as the treasure chests?

Yes.

it's actually below the treasure chests, there's another room below from where you see the table.
