A list of things I have published so far:
Perilous Places: The King’s Mercy – a location template for D&D 5E for a spooky-almost-sentient former prison. All of the money I make from sales of this product is being donated to the Alzheimer’s Society
Midgard Bestiary for 4E – I designed a couple of monsters for this book.
Bonus Bestiary – I designed three of the 12 monsters for this book
Defenders of Midgard – Midgard specific Player options for 4E D&D
Kobold Quarterly #18 – This was my first ever publication. How to run murder mysteries using 4E Skill Challenge rules.
