Well, i was pretty sure the wandering [world quest] in summer was Fotios, and the long winter was Atmos.(for bro @IamACD) but anyway, good job for you @Nosu.

You don't need Guardians DLC to run into Skoros. (I believe you recieve a quest saying that Skoros is heading for your capital city, and can be killed or told off by activating two titan bones boosters) In Guardians, there is a world quest where Skoros will wander in a random region, but remains peaceful until attacked. After you complete that quest by defeating Skoros, you unlock the technology for Skoros.

do you need gaurdians dlc? I was attacked by the middle one Skoros and couldnt build one after

We are fucked...

これはかっくいい…！(^O^)
