Are you going to railroad me by arbitrarily saying that there's nothing out there in the infinite cosmos that can possibly work to overcome?
how is that railroading????
Like...what??
Let's say an artifact gets destroyed. That artifact is gone! You aren't going to be able to rebuild an artifact created by a long-lost civilization using knowledge lost to time, materials nobody knows how to replicate, magic that is literally not possible to perform, etc.
Let's say a queen gets killed, and in the chaos following her death, the nation shatters and there's mass death from famine and pillaging. Even if you resurrect the queen, the damage to the nation simply
isn't something that can be wished away. At best, it will be generations of effort to put things back where they were. The PCs simply do not have the ability to just...wish that back into place.
Let's say part of your soul got destroyed. Souls can't be healed. You just...don't have that piece of you anymore. You have to learn to live without it. It's just gone.
You are making this argument circular by
asserting that a fix is always possible.
D&D is nearly infinite. If I can't die, it's highly unlikely that there's no way to overcome whatever happened.
It absolutely is not. There can be a million reasons why what happened has permanent effects that cannot be changed by the PCs.
If I lose something i care about, I can get it back.
How do you
know this for absolute certain?
A consequence is only permanent until I can find a way to reverse it. If I fail, I get to keep trying over and over and over and over and over until I succeed, because I can't die.
Except that there simply may not BE any way to do it. You may simply
not be able to do that thing. What if a
god dies, can your PC reverse that? What if the bad thing is the genocide of an entire species, can your PC reverse that? What if the bad thing is the destruction of an entire planet, can your PC reverse that?
You are simply, flatly
wrong when you say it's impossible for things to not have permanent consequences. They can. Death isn't the only thing like that,
and death isn't even like that in D&D anyway!
