Once more, Do'rhajul was quite reasonably surprised by what Sabine was telling him. The idea of towers that were somehow holding up Nirn seemed farfetched, and yet, Sabine presented it all with confidence. Do'rhajul's first instinct was to doubt her. It was still hard for him not to look at her as he had when they were enemies. He expected lies, manipulation. However, no matter how hard he thought, no matter what angle he considered, he could not think of any possible motivation she would have for lying to him. He had surrendered and was ready to march himself to his own death. He had already agreed to give Sabine and her allies every bit of information he had on Vile, so there was quite literally nothing left to gain from him. She did seem to want his aid, but if she was lying and there was no threat from Vile, then there would be no reason for her to want his help. The only way it made sense for her to be so adamant about it was if there was still a reason to fight. 

Beyond the message Sabine was trying to convey, there were also other aspects of her explanation that caught his attention. "Dominion researchers? Imperial contacts? We knew your clans were organized, and we had suspected you might have been receiving outside help as of late, but the two largest powers in Tamriel...I had no idea. Even if I had killed your Champion, I doubt it would have been enough. But aside from that, this sounds...well frankly it sounds insane. But you have little reason to lie. Truthfully, I am still not sure I understand, but you say these towers somehow protect Tamriel? But if the Adamantine Tower is his true goal, then why did he ever bother with your souls to begin with? I know that souls can grant power to a Daedra, but...no, that does make sense. Lycan souls are powerful; my researchers told me that many times. It was why it was so difficult to get the poison just right. Two beings, a soul and a, what was it, a...vestige, in one body. Direnni Tower is in High Rock, deep in Imperial territory. Even if it were not well-protected, which it is, I do not imagine the first structure in Tamriel would be so easy to destroy. And if what you say is true, if he wants to 'swallow' Tamriel, then that would likely require him to be stronger as well."

Finally, Do'rhajul willed himself to stand to his feet. "As terrifying as it is to say, I believe you. It means I not only was responsible for the murders of many innocents of your...our kind, but I am also responsible for putting the whole world, and everything within it which I once cherished, in more danger than it has been in since the last era. Truly, I would have been better off dead." He said, his eyes closed and his hands clutched into fists. After a few seconds, his eyes opened and he let out a slow breath. "But that is not our reality. You said you were here searching for something, yes? Is it some way to protect the last tower?"
