There was a very simple reason why Loimos had not made mention of what he told One to anyone else, it was because even he was not certain of the veracity, they remained but mere theories that the pure undead had not found the means to prove, some of what he said did not seem all that important… But some of it was instead of most dire importance, and here came another reason why none of it was ever spoken off to anyone else, as even if mere theories, one would expect the champion to share them with scholars or more ancient undeads who might have more information.
This was because the reason he had gone out of his way to gather strength was all to make a gamble, indeed, Loimos was gambling on being able to accomplish something based on nothing but suppositions, as solid as these suppositions may be- They were still not the undeniable truth, but at this point, there was little room left for thinking and preparing.
