Nobody would respond on the zelda forums so I'm putting it here. Where are some possible locations to use the magic mirror so I can get back to the Dark World? I used the mirror while in the Dark World, then left the spot to get some heart containers. Now I can't get back to that spot. Are there spots in the world I can just use at any time? Any help would be appreciated

The Magic Mirror is a one-way portal, as I recall. The only way to re-enter the Dark World, aside from the sparkles that float around the spot where you used the mirror before, is to find a portal. They're generally found under rocks in important-looking places (dark rock in the middle of a circle of light ones is a good bet, iirc.)

Do you where any portals are located specifically?

There is a portal on death mountain I think its under a rock near the top.

I think this will help you out.

There is a portal in Hyrule Castle. Just walk though the large gate that leads through the castle outer wall.

Thank you KoolAid. Your advice worked. I thought I was going to have to start the game over. Also, the portal at Death Mountain doesnt allow you off of Death Mt. at the point in my game.

Please don't create multiple topics about the same matter. One will suffice, and our forums work in a way where everybody can see just about every new thread. Thanks!
