The tibian chaos warriors were a guild which formed possibly around Beta 5. Snikch, the only person I could find who was in the guild and possibly the founder held the title of Supreme Commander. Under him was the Commander's Right Hand, Supreme Assassin, Guild Treasure Guardian, Assassin Squad, and finally novice. We know very little about this guild apart from their structure and their code which is below:
"The Code :
No member of the Tibian Chaos Warriors may harass, attack, or kill another member unless challenged to combat!
All members are obliged to help each other!
The guild treasury lives on voluntary donations ( gold, weapons, helmets, shields, etc. )
Every new member gets a complete set of gear!
Anyone who violates the law will be punished with death and will immediately lose all the armor they are carrying!"
