I will say this first: If you wish to make major changes to my projects, simply by threatening veto until I give in...well, that's simply unfair, to put it in what might be a childish way. For major changes to my systems, as you and your predecessor Yaos have both demanded, require some contribution to the project. However, your suggestions are not unreasonable, and so I will give you the compromise of your compromise.
I was actually planning on having them 'move' in a sense anyway, though I believe I didn't make that evident when creating them. Major intersections would likely remain the same, simply to ensure places of power and to allow structures built to utilize them do not become useless.
Second, first allow me to say this: Ley Lines cannot be utilized on accident. That will certainly be a point. Magical effects may occur naturally, but this will probably be more in line with hot water geysers of healing water or swamps of hallucinogenic gas that lets you fly than random explosions and Death Zones. Some may be dangerous, yes, but in an obvious manner, and no more than any other dangerous place on the world. And like at intersections only, where the magical energies are particularly high; a reason I wish for intersections to remain mostly the same, so that these features can be mapped and documented to utilize, avoid, or redirect their effects. However, they can be accessed by those with magical talent, and those with magical training. Does this have the chance to burn their bodies out? Possibly. I'm very foggy on that subject. But it will almost certainly not burn out their souls, since that occurs from using the soul for magic, rather than simply utilizing a separate power source. I say this because in order to train new Geomancers, the apprentice will need to be able to access the Ley Line before they are fully trained.
I will endeavor to make them in such a manner as to avoid influxes of power overpowering those who cannot control it, by making it something like a river, rather than a pressurized pipe; you can dip your cup in deep if you like, or only a little at a time. The only way you are likely to be overtaken by the current is if you are thrown in and left to sink or swim. And I'm fairly sure the only purpose someone would have for doing that would be murder or a final test of training, as I believe it would be rather complicated to force someone open to the Ley Line in that manner, and the second one would hopefully have the mentor ready to save the pupil if things went badly. I cannot control all things mortals do, sadly, and if a mentor was truly so heartless, they could do a similar sink or swim test in any case using other methods and kill their student that way as well.
Does this satisfy you, God of Souls?
Darruth looks rather amused as he says the last bit.
