In the city, he co-designed the ghost pirate jumping puzzle with Josh Foreman.He designed the translatable alphabets for Ascalonian, New Krytan, Asuran script, and Orrian syllabary.Dead quaggan puzzle.He created the "Flying Dolyak" race of the first Festival of the Four Winds.Worked on several story instances, including Arcana Obscura, Prisoners of the Dragon, The Sacrifice, and A Shattered Nation (the last story instance he worked on).
