why did he came alone then?
I don't understand. Could you reword that so it makes sense? Does a missionary need armies to convert people?
Will be hard to start a religion on your own.
Perhaps, but the character has already found people interested in the faith. In Madina.
When you start it just make sure it is not called church of 'humanity', or any other ridiculous name.
How is "Church of Humanity" ridiculous when our characters are based in worlds plagued by marauding bands of Undead, Monsters, and Daimons/Demons (not to mention the occasional elf on EC)? If anything, based on the surroundings, it makes perfect sense. Especially when there ARE daimon worshiping cults out there.
While I understand Dwilight is the "Serious Medieval Atmosphere" island/continent, it's still a medieval
fantasy environment, so long as there are undead, monsters, and daimons lurking about. Not to mention the wizards that Adventurers can find and the scrolls that enable us to cast magic.
Don't get me wrong, I'd love for a BM island based on Europe/the Mediterranean region with bandits instead of undead and rogue mercenary companies instead of monsters... But I don't see that happening any time soon.
