Tower Entry
Greetings traveler. 
Your wanderings have led you to my tower and you are welcome inside. Tread with caution if you enter, for if you do, you will cross the threshold from your world to another—one of subtle magic and tenacious inhabitants, with creatures of sweetest dream and darkest nightmare.
There, mysteries come alive and the lost are found. 
Here is the preface to that world, as it were. A foretaste. Will you partake?
You may enter by the doorway. 
If you hesitate, you are right to do so. Travel between worlds is no small thing, and indeed, it may seem impossible. Yet the journey is worth it, and though the exploration may merely entertain, it may also be the catalyst of freedom.
