*What went wrong?
When walking to the island connecting 3 lvl 90’s monoltihs i expected to have empowered timelines unlocked, but nothing of sorts happened. I was running around and to each island again and still there was no way to activate the altar (no cutscene or anything). It fixed itself when i teleported to “reign of dragons” and walked from there, instead. Very weird and probably unintentional so i’m posting it here 
Thanks!
