The Dweller. Prophet. Statistician. Sometimes madman. It is unclear, even to himself, whether he is seeing the future or calculating probabilities better than the fastest computer in existence. Needless to say, The Dweller knows things, often before they happen.
Knowing and not saying…I would NOT know how that feels. Much less how it feels for it to be long enough ago to be certain I have absolutely idea what it is I had no knowledge of. iow I have possibly perfected genuinely erasing a memory. I forget.
