Well... I created the Arcane Knight and Eldritch Blackguard combat traditions, there's the Zevites, the "Living at the Edge of Night" article with backgrounds and destiny, the Zephyr's Complement which you noted, the follow up of The Zephyr's Legacy: An Airship and her Crew, Streamlining your Dungeons: Delving Activities, I also created some monsters for the Monstrous Menagerie 2, added some backgrounds and other material for the Voidrunner's Codex, and wrote 1/3rd of the Escape from Death Planet adventure packaged with the VRC. I also helpted to write the Vault of Shattered Souls for EN5ider.
And then there's my third party work, mostly with Purple Martin Games. Together we wrote the Spells from the Forgotten Vault, System Architecture: Motif Classes, and I contributed to Manual of Adventurous Resources: Complete.
And I also wrote the book Paranormal Power: A Psionics Option for 5e and A5e which added a new class, heritage, psionic heritage traits and gifts for the core heritages, new spells, new monsters, and a new Martial Tradition.
