That made sense. Although he thought the mark might be recognition aplenty, he certainly didn't want to take any unnecessary risks. "So am I supposed to get some black robes and start chanting in a language I don't-" And it was right about there when he realized he did in fact know the language the chants needed to be in. "-a language I apparently know very well?" He knew there were other possibilities, but didn't want to think of them. Being a vessel for Azathoth was not something he could think about without losing it.
