There are several Gods. And each one of them has his very own henotheistic
Here's the thing. The Gods know that the mortals misinterpreted their Words, so the current Religions are corrupted bureaucratic caricatures with more paradigms and setbacks than virtues and advantages. And they are ruining the world. So the Gods sent you to destroy them. Permanently and in form, and not just in name. For the Greater Good.
The Gods are practical. What matters to them is the end result, not how you reach it. They are more concerned about ending Dogma, customs and what people do, rather than what people believe or think. And the means are entirely up to you.
Your success is practically warranted. Whatever you try, you'll succeed. It is more a matter of how will you do it, instead of whether you'd be able to or not.
So, with that in mind...Phase A.
What would your big, ambitious, world-changing plan be?
How would you destroy Religion?Phase B.
Break down your big plan in easy
10 steps. What would you do first? And then? And afterwards? What convoluted and machiavellic (or direct and practical) actions would you execute to reach your objective in the end? (Remember. You can assume anything goes the way you want it to.)
