Portable stairway to heaven
The Portable stairway to heaven is a bold artifact. Almost everyone has heard the famous advertising jingle for the permanent version of this model, but have never put an actual down payment in order to start the process of building one for themselves. Very few heroes have ever seen an actual stairway to heaven in their life, and if they have, it's not a good sign. Here you have yourself a portable one.
Take it wherever you go and pull it out whenever (and wherever) you're ready to use it. Voila! Just go toward the light.
Fun for the whole family, but it's a one-way trip. There's no coming back unless this is some fantasy about alternate universes...
Some assembly required.
