"“No one knows where The Tower comes from. Made from glossy cobblestone, windowless, and massively tall the Tower appears, seemingly at random, on different planes at different times. Its door only opens to those it deems worth of its knowledge. Upon your first entry, you’re greeted with a lectern holding one of the oldest books found within The Tower and book cannot be removed from the lectern. This is The Tower Guestbook. While one might expect a normal guest book to contain a record of all those who have visited, this book records their history, intentions, and most importantly, theirspells. This excerpt contains the records of 8 spell casters who have visited The Tower, each a master of a primary school of magic. Their history, spells, and notes have been preserved in this record for those outside of The Tower, so that the knowledge of the arcane might be explained, and so that more worthy of the arcane arts might grace its halls. May you one day be worthy.” - Bartholomew Silverquill
