So here's what happened immediately after i got the notice, I happened to be near the GE so it was the place to go for "answers". This is what I found.
Well this is very descriptive.... lol. (Lol at the guy who's trying to buy mithril boots XD)
So I went hunting around for clues, and immediately I went to the Frozen Door in GWD. I tried everything that made sense to open it; getting the kill count of all (or as I like to call it, the omnikc lmao): Sara, Zammy, Arma & Bandos. But still it wouldn't release its cold and frigid hands on the door.
Then I went hunting around and talked to all the mystics I could think of. The only ones who noted this phenomenon were Peer the Seer and Baba Yaga. And all they said was something to the effect of "Ughhh what was that darkness?" then went straight to the "How can I help you?".
Well I didn't give up there and I went around and heard rumors that were intriguing. Rumor had it that the Cosmic Alter has changed so I got out my Glory and went to the abyss! Here is what I found:
WHOA! It turned out that the "mysterious ruins" at the Cosmic Alter had turn a powdered sugar color, a sort of chalky white. Also, it is glowing purple instead of its normal yellow color. I thought to myself "Self, what if Jagex had just changed the graphics on ALL of the ruins?" So I set my course for the Air Alter because its very convenient, and lo and behold! The Air Alter was its regular grey color! So what could this mean you guys? I personally have no clue
