Deep in the mushroom forest, hidden from sight, was a blue, luminous portal. With a perfect placement of rocks and long weeds, the portal's light could not spread far. Because of this, few creatures could manage to find it.
One of those few creatures was the owner of said portal, a white tiger with wings.
Holding a dead goat in its mouth, the white tiger entered the portal. Of course, that was not before the tiger erased all traces of itself.
Whoosh!
With a slightly disconcerting feeling passing through it, the tiger went through to the other side of the portal. Which was a great contrast to what was going on outside.
