Not directly, at least - the very last Adams and Eves would've died before YOG 200, and gunpowder wasn't introduced until YOG 805, and all the memories the Adams and Eves had had should have been lost. Khody had some leakage, but that was probably a result of the seijinization process, so it'd've only applied to a small, select bunch - whose journals and diaries would likely have come in for special scrutiny by the Angels for anything of the sort.mhicks wrote:Two thoughts from reading this thread.
1) Could the gunpowder come from Adams remembering the product, it's use and formulation/name? (One of the Adams might have been a historian who liked making black powder muskets as a hobby)
However... it may have been experimented with or even outright approved by the Church for use in the War Against the Fallen. If they tried to put the genie back in the bottle after the War, they may not have managed to succeed perfectly and may not have given gunpowder the same "no, no, not ever" specific sort of anathema that electricity got in the Writ. (It's less of a "gateway technology".) If they didn't, then records of it and its manufacture - even incomplete ones - may have resulted in its rediscovery later on.
2) When Archbishop of Glacierheart escaped through tunnels that were older than the maps of the mines in the area, I wondered if there weren't more mines out there hiding a module. His mine was long and deep and run out of resources. It made me think that it was dug before or during the war of the fallen from how it was described in the book. I wondered why it had been dug in the first place from it's description.
Several hundred years' mining in an area would likely create a lot more tunnels than maps or memories of those tunnels. I wouldn't rule out War era tunnels, or leftovers from the terraforming process, but there's a whole lot of history available to get them made and forgotten after those times too. It'd be quite a coincidence for one of those tunnels to be both the hiding place of one of few or one such modules and the escape route of the Archbishop of Glacierheart.
