I'm interested! May I suggest you leave links to various source materials about the era you are trying to portray? It may help those like me who are no history buffs but enjoy learning about it anyways.
After thinking about it, I have decided that the vague craving I have for a tribal rp could very well also be with a small (four others at most) group, and I will thus leave the link to the original search here, assuring you that this could be a bigger project if enough are willing to work together with me as a group to make this dream a reality.
This is still a very involved thing, and some more heads and writing talent may very well make a big difference! If interested, feel free to say so below.
