So… I don’t have a story quest after the revelation of goddess saule and I entered the portal.
Not even in the quest list (F5)? The next step of the main quest asks you to go to Rukas Plateau. You are sent to Gateway of the Great King so that you can get there and level up a bit on the way (do some randon quests and stuff). Maybe once you get to Rukas and talk to Historian Rexipher it appears on the track again.
You have to be lvl 63 for the next story quest at that part.
Keep moving forward.
Check a list of maps per level, and pay a visit to any you may have accidentally skipped. Mainline quests will reappear once you reach the proper level.
