There's a very bizarre place in the Czech Republic that any campaign setting builder would benefit from adding. It's called the Sedlec Ossuary and it's a small chapel where so many folks wanted to be buried that they needed a new way to accomodate all of the skeletal remains. During numerous reconstructions and expansions, bones were moved here and there but eventually, in 1870, a woodcarver was hired to put the whole place in order. What he did there is both innovative and very, very creepy. Some might recognize it as one of the settings in the Dungeons & Dragons movie. Read more here!
