The Communist Party of Tibia (KPT) was a guild which was founded in Beta 4 though not much from this guild remains. I recall from my reading that they had some very good resources on their site including a copy of the game editor program. One of the pages that we can read remarks that they felt the game could use a Runescape style of manufacturing where players craft their own items by mining resources like coal, an idea that CIP supported as a future feature in their Beta 6 future plans section. Perhaps the guild was founded to promote these types of ideals? RSST lists their guild link description as the tagline "Newbies unite!" so maybe this was related to them in some way?
