Ok so I was messing around with word the other day and happened to type the letter "c" in Wingdings 2 font and the Eld symbol came up; very weird.. I also noticed the symbol on a university's faculty of arts banner.
Just out of curiosity, does the symbol of Eld mean something else outside of the dark tower series? I'd imagine a high profile university wouldn't have a random symbol (that no one other than DT readers) would understand in the faculty's banner.
Here are the links to..
