Unseen University Postcards - The Chapel

Wizards don't find it necessary to believe in gods in the same way that most people don't find it necessary to believe in, say, tables.  They know they're there, but they don't find the need to go about saying "Oh Great Table, without whom we are as naught".  Wizards also don't take chances.  That's why they have a chapel.  There's a large window in the south wall, and a stone archway containing a wooden door is to the north.
