Sinfar was created by the goddess Sinfera at the precipice of time, through the merger of numerous primordial realms. It used to be accessible through Planescape (we even had a few planescape areas which are lost to time). Originally Sinifer City was ruled by King Seth but at some point in beta he died. (his NPC is still in the database somewhere. he's a lich now)
Lotus Isles originally had a problem with vistani gypsies. The isle was originally ruled by Empress Genki who had a rivalry with her brother. Wgeb Genki went missing the council of chairs was formed. each chair was based on an element.
There were two wars with Saban. The first was nothing to speak of. The Second was fought between Sinifer City and Saban. The war wasn't very long. Hapto and the Angelf d'eath family were involved. Hapto supported Sinifer, Angelf d'Eath supported Saban. It was at this time house Au'Tic was formed and served Saban. The war ended when Sinifer surrendered. At the King's victory speech he was murdered by a man named Jan who rigged an explosive device under his throne.
After the war with Saban there was a short war with the Netherbeasts, inter dimensional fiends who could only be damaged with cold fire weapons. The battle had no real resolution. (DM Quit)
Hapto was the first major merchant's guild in Sinifer city. They aren't very popular. They owned an island which still exists to this day. They also funded the creation of various smaller islands and areas.
Anyone remember Talon and his crew? They fought dragons and had a flying ship. Vincent owns that flying ship now but probably isn't fully aware of it's history.
The Berry clan is a forgotten clan. They used to live on Cat-Ta-Berry which was originally named The Shire. They were born from pods which sprouted from large plants. Initially they were only able to breed female Berries. Members include Ashberry, Strawberry, Blackberry. (you'll notice a trend here)
