In the Forsaken ViDoc we saw a bunch of things, but a big one was actually a Guardian driving the Silver Tercel atop the massive bridge leading to one of the towers in the Last Wish Raid near Shuro Chi encounter. Here we are approaching on three full seasons since and there’s no way atop that bridge. Is this cut content? Are we going to see this sometime, if ever? Because to show that and have it not be possible is kinda messed up.
It might be in the future. We probably need both Light & Dark to open the way to the Distributary for Savathun. Like how Uldren used it to open the Dreaming City and how the Blind Well opens the Shattered Throne. Darkness in the Dreaming City is covered, but Light in Eleusinia isn't. A direct way to go to the top of Eleusinia's tower for story purposes would be to have a story mission in the Dreaming City to the top of that tower, then teleporting to the Ascendant Realm from there with our maxed out 999 power level that'll be stripped away probably like in Savathun's Song.
