This work is a combination of two works, the D20 System Reference (version 3.0) by Wizards Of The Coast, and the Open Gaming Content from Fantasy Flight Games "DragonStar" campaign setting. It apparantly is based on works from http://www.zombler.org/ so I have included thier logo on each screen. I could not find an email from http://www.dragon.ee, with hope, they'll have no issue with me borrowing from thier fine work.
The first is the "D20 System Reference Document for 3.0". The majority of the 3.0 SRD work comes from there, with some heavy changes to style. It is an excellent work, I heartily recomment it.
The second half of the work is based on my own efforts to strip the Dragonstar campaign setting of its open content rules, and combine them with the 3.0 SRD to make a complete "Dragonstar SRD". I hope you find it useful and enjoyable.
