I have replaced the 'moon elder' (near west gate) with a custom NPC ('Chapel Guide') that will teleport you into the chapel foyer (formerly waiting room). Another custom NPC is located in the 'foyer' that will take you back to archosaur, or into the chapel if you have a wedding invitation in your 'bag'. The newly created wedding invitation item is given to you when you open either the bride or groom packs, so whomever is getting married can pass them out to whoever they would like to be able to come in the chapel with them for their wedding. The 'moon elder' is now located in the chapel, so you must go inside the chapel to get married or divorced. There is also another custom NPC in here that will take you back to the foyer.
