Naseli's pretty fun. I wanted to play one for a while. I'll be interested to see how it actually plays in practice, so I'll definitely at least read this campaign as it's going along.
The premise is definitely interesting besides. The first thing that popped into my head was Binder, and then saw that you addressed that in the houserules. Also glad someone else had the same thought and was considering it.
Thanks! This unoriginal idea is something i've been wanting to try out for a looooong time... I just like the period so very much, and i think it is so D&D like, that i thought... Why not try to do it, but put my spin on things?
This looks pretty sweet! I has some ideaz:
Thaumurai
Astronomer
Nomad (possibly with some brewed disciplines)
Jester (possibly with some brewed disciplines)
War Frenzy
An evil astronomer?
I guess from the Church's perspective, Galileo was evil, so that's hilarious. You should think about Precession's Guide.
Wow, there's so much interest in homebrew, i didn't expect that... I'll have to get back later, there's many things to consider, and i didn't even analyze the alternate martial disciplines yet.
Someone also asked about levelling up a few posts back...
I'm not a fan of eternal waiting, and i like to reward ingenuity a lot. I don't do XP based on encounters, but rather i do everything Ad Hoc. Sometimes you'll get through a series of battles and win very little XP, and sometimes you'll get through a den of Kobolds without a single battle, and win a big amount of XP. It all boils down to how much effort was put into overcoming the challenge, how original the way you overcame it was, how much resources were spent in overcoming it... Roleplay also gets awarded XP, as well as all sorts of minor things no one even bothers paying attention to, like weaving the character's backstory into his actions and stuff.
I played a lot of Storyteller, and i was a big fan of how they did things. Picture the campaign as divided into "Scenes". Everytime you go through a "Scene", you can expect a level up, or even two, depending on how long or hard it was.
I don't know exactly how long it takes for an equivalent of a 4 hour session in a face to face D&D meeting, but expect a level up roughly every 5 or 6 sessions, since it's what i usually do in RL games. It's not extremely fast paced, but not really slow either.
For this adventure... I'd say maturing the character at or near level 6 or 7 would be a good idea.
