Help a fledgling GM start up a semi-dystopian modern day 'magic attacks technology' campaign?

I really enjoy the concept of Ilona Andrews series about Kate Daniels, though the romance aspects get to me a bit. In any event, I think the idea of magic returning to the 21st century, screwing up high technology, and returning the myths and legends to modern day is an awesome post-apocalyptic scenario and I’d like to develop a campaign in a similar world but I’m not sure what steps to take to make this work well with OL-RPG

I have experience with D&D 3.0/3.5, GURPS, and the recently released OpenLegend RPG but I am a rather inexperienced GM.

Synopsis of the world that is my inspiration for this:

The world has suffered a magic apocalypse. We pushed the technological progress too far, and now magic returned with a vengeance. It comes in waves, without warning, and vanishes as suddenly as it appears. When magic is up, planes drop out of the sky, cars stall, electricity dies. When magic is down, guns work and spells fail.

It’s a volatile, screwed-up world. Magic feeds on technology, gnawing down on skyscrapers until most of them topple and fall, leaving only skeletal husks behind. Monsters prowl the ruined streets, werebears and werehyenas stalk their prey; and necromancers pilot blood-crazed vampires with their minds.

So I’m basically thinking this is something like “Revolution” the TV Show but with magic as a new scary thing that caused the failure of technology.

Hi @llewinidas.
You’ve posted this thread under Rules Discussion, but I can’t see any rules questions in your post. Was that a mistake?

Also, your question seems to be about what system to use for this campaign; given that you’ve asked on the Open Legend forums I think you can probably guess what my answer will be…
From the description you’ve given, I don’t think this world even requires any changes to the rules to work properly. Is there a part that you’re struggling with? If so please let us know what specifically is causing you problems and our community would be happy to help.

I think OL would work Perfectly for a world such as you described.
When Magic is bountiful add Disadvantage to any roll to do with Technology and vise versa when its depleted.
Think this adds an interesting dynamic to the OL system and is a great concept for a game.

Thats fair. The OP was cut/pasted from a more general rpg community… I have edited to clarify an OL-RPG specific request for help :slight_smile:

Thanks. It seems like a really fun idea to play with… I’m going to move forward with it.

In a normal world situation if you brought 21st century weapons (M4 carbine for example) to a ‘medieval magic’ world the weapons should get advantage by default for being Tech lvl 1 instead of Tech 0, yes?

If you want to use that rule, yes. Remember that the advantage only applies in situations where the difference in technology is relevant: you probably wouldn’t give advantage 1 to the rifles versus magic, and medieval weapons wouldn’t get disadvantage against an unarmored target.


I agree with the others who said you probably need to do very little (if any) rule tweaking to support your setting. I recently created one for my new Open Legend campaign, and I didn’t have to make any changes to the rules to accomodate it. One of my favorite things about Open Legend is that it’s nearly always enough to establish narratively how something works, which lets you make an action roll with the appropriate attribute when needed.
