Plodding along through Waylon Way, and at the top let I saw what looking like a little sparkly volcano (no other way to describe it). When I jump on it, I got a new quest like the faded heart deal - 11 new hidden places to look for, tied to each giant. It gave me a bonus too: "You feel the power of Cosma vibrating the air in your bronchioles. This is one crazy DNAja-vu.You gain 50 favor with Cosma. You gain 100 xp."
Pretty cool! Not sure is this is new or not but I can't find it on the forums...
