That sounds like a really interesting setup. Did you each get a profession/craft to base a few skills around?

Very good points, Thank you!

I guess the most canon-compliant way to make this idea work is that they were a cleric of a deity that died. That does happen in DnD settings sometimes and I would expect that would remove their access to divine magic. Of course I would expect that rules would let you substitute a different deity with similar domains, and there are definitely skills and feats you wouldn’t lose with your magic, but it would be an interesting backstory.

I think there’s also a fun opportunity for the world to just evolve a lot in that time. Like, you were a wizard 100 years ago, but then spells were super different and way less powerful, so now you get to relearn the newer better spells and casting techniques. I imagine it’d be like learning to programming 50 years ago and then starting again now

I like this one

The thing you said that someone disagreed with was calling it ionizing radiation, which is a more general term and describes radiation with enough energy to ionize an atom or molecule, which means stripping off at least one of its electrons. That requires a lot less energy than activating nuclei in an element that is not radioactive to radioactivity. UV light and X-rays are both ionising radiation, but are not from radioactivity and cannot induce radioactivity. Of course a lot of radioactive radiation (α, β, γ) is also too low-energy to activate more nuclei. It depends on the energy of the radiation and the specific element you’re trying to activate (how close it is to being radioactive, so to speak).

So like CommissarVulpin said - the real danger is more likely to be contamination

I second hedgehogs for Germany, they’re so cute! Also, or squirrels are so different from the US kind, they’re just unfortunately a lot shyer, too

I used to eat a pasta sauce with canned tuna that also had onion, yoghurt (or cream) and capers. Depending on the amount of effort you want to put in, maybe just adding some capers might work :)
