Gods and Immortals in games
Ok, so first, thanks for all the help on the poisons/venoms question I had for my homebrewed game. I now know how to work it.
But here's another issue, as the title suggests; how to handle them in-game.
I don't intend to come up with a full pantheon or anything as I won't use most of them anyway, but I do have one that would feature, mostly in some subtle way. But here's the tricky part. Though I have some ideas, hhow do you feature an NPC that cannot be killed or harmed in a game without unbalancing it completely? Having him give out a quest/mission seems like a plan, but are there any other ways?
To give you a better idea of what I mean, the character in question is Ankou, the spirit of death, much like the grim reaper of western European mythology. Ankou differs in various ways and that myth is fascinating to me, enough that I want to use him in some capacity.
If it's not obvious by now, I haven't run a game before and could use advice on how not to trip myself up for when I eventually introduce him. It should go without saying that he will not be a villain or enemy in any capacity.
As stated, I do have an idea on using him as a quest giver, maybe to help him as he's been somehow bound, maybe something along those lines. But what (other than making him a villain or ally) should I avoid doing?
