Thank you for considering Haphazard Projects, home to the DPS System.
The DPS System is available to freely adapt into whatever works you desire. An SRD is in the works.
Also note - The Aethyrblood Chronicles is about to receive a major update. Increased page count with more details on powers, organisations, and full character sheets for NPCs. This will be a free upgrade for any who pruchase the game at any price.
