As everyone should know, the main characters that function and keep the flow of the game moving (like Mario and Al-Maulim) are the only ones actually in the RP, which, you still should know very little about.

The only people not in the RP for the both are Altair and Ezio, aside from Altair being mentioned in AC2's section (due to the codex pages being scattered and required for advancements in the Assassin armory.)

So, try to cut these two out of your RP knowledge. You can hear of their actual presence (Ezio would be known as a nephew of Mario), but not of who they are. If they are mentioned, they will normally only be done so to forward an RP by triggering events.

Again, try to avoid connections to Altair and Ezio. Other than that, we're not seeing much more problems about one-liners (that aren't needed or unavoidable) and fighting between members.

Remember: If you have friends that know how to RP, invite them. A more experienced RPer can teach them how to RP if they wish to better their abilities.
