It was sort of an early in joke with the arg that has now been absorbed by it as far as I know. Thats why there were noodles given out at the live drop in NY. I’m not sure the exact circumstances it came about as I wasn’t here for the first two weeks of ARG but also as others pointed out it conveniently is an anagram for old ones.
Some of the earliests teases for waking titan were lovecraftian in nature, referenced stuff from abandoned buildings quite a lot, and seemed to hint that waking titan was basically waking an old one. More hints to this being the lead moderator of ETARC is caled OLDGODS and his location are GPS coords where R’Yleh is supposed to be, the sunken city were Cthulu slumbers.
For a while the Old Ones reference died off but recently we got Call of Cthulu by metallica as a video link, and someone I believe figured out the un used numbers on the decoder wheel converted to gutiar tablature and were the first few notes to the opening riff of call of cthulu.
Okay so, why were they sent from themselves? Well, because they sent it to themselves! From the future! More time bending ARG stuff Love it!
