Real Life Inspiration
The NPC Carlo Williams is a tribute to British author Charles Williams, member of The Inklings along with notable authors and professors such as JRR Tolkien, C.S. Lewis, and Owen Barfield, among many others. The Inklings regularly met in the real life London pub, Eagle and Child (often called the Bird and Baby).
In the NPC dialogue during the quest Missing the Meeting, NPC Carlo Williams mentions his book 'The Place of the Boar' which is a reference to Charles Williams' book The Place of the Lion.
