Endrance sealed

[deltanog]

I had a question, and I never saw a sensible answer. In my mind, after Endrance lost to Haseo, and consequently lost "Mia," he sealed himself because he felt powerless and no longer needed by anyone, since he thought he was only needed by Mia. So he went and sealed himself in the Lost Ground (The Dead World of Indieglut Lugh). But we saw that Saku at the beginning of Reminiscie talks about him never leaving there, and then before Haseo appears, she uses an item to make the sarcophagus with chains appear. After Haseo defeats Gorre, the chains are wasted, and then he has that conversation with Endrance. But the question that comes to mind: did he seal himself there, or did he, and then Saku sealed him with the chains? And while he was there, was he in a coma? Or was he logged in for 24 hours without eating, without logging out of the game? This is something that leaves me in doubt.photo of the scene
