Go to the Misty Ruins

After a long journey, you arrived to the Misty Ruins
The place is covered by a mantle of thick mists, it's hard to walk and you think that you can be ambushed at any time.

You explore the ruins searching for a clue, and you find a creepy wizard tower.
It seems abandoned, with layers of dirt but when you are closer, you notice that is an illusion!

The inside of the tower is clean, and a strange cylindric artifact glows in the middle of the main room, there is only a silver mirror and a table with an old scroll.
You read the scroll and says "Speak the name of your world, hold the artifact and the portal will open"

It's too easy, maybe it's a test?
You have to decide: Say "Hello", let the wizard know that you are here, and ask for help or steal the artifact, use it, and try to come back to your world.
