This mod looks really cool, but I have a few questions:

1. Can this mod be used on an existing save file, or would I need a fresh start?
2. Do the Fulgoran enemies respect Peaceful Mode and Enemy Expansion settings?
3. Can this mod be removed from a save file safely?

I really like the idea of this, but I'm worried about adding it to my current run and also about getting overwhelmed by aggressive enemies :)

1- yes, but they will only appear on future generated chunks
2-I think it does
3-Yes

Excellent! Thank you for the prompt response. I've not yet landed on Fulgora, so all chunks should be newly-generated. And if they turn out to be more agressive than I expected, then I can just turn them back off. This should work.
