Aye I saw this months ago as well and was promptly concerned about what articles we were having to sign or what ever oaths we were going to have to take. Neither of which appeared at the induction ceremony unless I missed them due to being so late to the affair. But when speaking to Stynky, upon arriving, he said he had not seen anything regarding said articles either. So all worked out well to my advantage regarding any questionable wording... Stynky and several others were well aware that I would not be signing anything, even in jest, with any such ties to a satanic cult.
Talderoy will have to speak up for this himself, but odds are the name of the order has nothing whatsoever to do with the satanic cult. Most likely just a name that has more punch then the Order of Mermaids/Mermen...
