Portal to the Dyrad Forest

{t}{2}{g}You open a portal to a forest of an
unknown plain, where fairy-like creatures seem
to roam. Only you can see the world around
you and interact with it. When the portal closes,
you are trapped in the forest with no knowledge
how to re-open it.
"Where I come from, portals to another world don't
just appear behind a random door." - Igor
