For those of you who aren't familiar with Doctor Who please feel free to slap yoruself. After you have done that look it up and love the good doctor. Now for all of those are familair with the Tardis I would like some ideas on what it would take to build it using the Stronghold Builder's Guide and what ever ideas pop up. Now it seems simple enough to do, but looks can often decieving. We are looking at a box that has an inside much bigger than the outside. While it has no active defenses it can withstand hordes trying to break in and can only be opened by the doctor. Mix in the fact that it can travel all through space, time, and (at one point) dimensions and it seems simple enough. Time, of course, won't factor into this but teleportation and planar travel will. So, any thoughts?
