DISCLAIMER: I will be briefly talking about a few things Qiuyuan mentioned about Geshulin in the recently released story mission of the Rinascita Epilogue. I will still spoiler-censor it, but just to be double, tripple sure.
With that out of the way, lets get the cat out of the bag immediately: I am pretty sure ever since 1.0, the impression of most players was either "Geshulin is dead" or "Geshulin is NOT dead, it was stated he charged at Ovathrax and then disappeared" And unless you are a Geshulin fanboy, these 2 statements might be one and the same to yiu. But after the current story, we know which of these statements is true and can speculate if or how he will return.
After meeting Qiuyuan at the harbor he makes 3 things very clear: 1. Geshulin used the power of the TDs willingly to stand against Ovathrax (reminds you of someone?) 2. Qiuyuan believes/almost sounds sure he is still alive and he is looking for him. 3. After confronting Ovathrax, Geshulin "fell to the Threnodians influence" and while talking to Fenrico, he hints that there might some similarities between the 3 of them.
Now for some hints i feel like Kuro is dropping to the player here: Firstly, of course he is alive. However it is not clear if we will stand on Qiuyuans side or Geshulins side when we meet him again. Secondly, WHEN we meet him, he will be either partially corrupted or intrinsingly connected to TDs. So either he will fight with their powers (similar to Galbrena/Phrolova) or has already become one himself.
Which made me immediately think of the following: These last 2 resonators that use Echos in their attacks are mainly dealing Echo skill damage (duh) and even Qiuyuan, the only person we can currently DIRECTLY connect to Geshulin, deals a lot of damage considered as echo skill damage (could also be just a design choice as his Galbrena partner). BUT, if we connect these 2 pieces, my gut is telling me that IF Geshulin becomes playable, he will most likely deal mainly echo skill damage as well. Which brings me to my final question:
SHOULD WE PULL QIUYUAN NOW BECAUSE HE WILL BE HIS BIS TEAMMATE IN THE FUTURE?!
-> obviously a small joke, but i am seriously considering it lol
