As many of you know, Prince Uldren was resurrected by a ghost named Pulled Pork. Here is the video https://www.youtube.com/watch?v=evJPzdkwy04 . For those of you who are not lore enthusiasts the first instinct a guardian has after first being resurrected is to travel to the tower. Uldren has not made it to the tower yet so it is 100% safe to assume that there is something preventing him for doing that. We also know Uldren was resurrected during the dreaming city curse. I don't know if guardians are immune to the dreaming city's curse or not but Uldren was a corpse in the beginning of this curse. If we assume that Uldren was resurrected during the first 3rd week of the curse then it would explain how Mara eventually found him being resurrected. She just found him walking around and traced back each 3rd week until she found the location and time of his resurrection. I think this is kinda funny, every 3 weeks Uldren gets resurrected gasping for air and removing that cloth over his face. Uldren will finally make it to the tower when the dreaming city curse comes to an end. Hopefully that will happen at the end of this season.
