The last time I did this, two of the PCs were cousins (or brothers? . . . there seemed to be some family rumours which made the whole thing a bit unclear), samurai from a fallen house. Another PC was from a merchant family who funded the samurai brothers in return for fostering this third PC as a warrior. A fourth PC was from a merchant family who hired the samurai as bodyguards for a mission. And the fifth PC - a fox-spirit - was the guide to lead the group over the hills to their destination.I'd require all PC siblings to be the same race, probably human. Other races could maybe be retainers of the family.
En route they met a sixth PC - a tree spirit - who joined with them for reasons that were never very clear. And later on in the campaign a seventh PC - a monk - was sent their way by a prophetic dream.
Out of curiosity - given that you, as a player, presumably knew that you decision about how to play your PC was in danger of disrupting the game, why did you not decide that you had a dream, or some other intuition, that going with this priest was what you were destined to do?I've refused to meet the party once. The DM gave the cleric of Tempus an item hidden in a box and told him to hire people for travel. I would have gone along with about anything, but I couldn't in any way justify as a paladin assisting a CN cleric in transporting an unknown item. Eventually the DM tossed my character a dream to tell me it was okay.
