Definitely writing a book with undead protagonists. I should bring back the Sinless, write down that setting's details
The Sinless were criminals, sentenced to death. Stabbed through the chest with ritual swords in public executions.
Some simply die, but the lucky are reborn as holy warriors, their memories blank, slate wiped clean. The plain ritual swords absorb their sins morph into unique, ornate blades, their only shared trait being the shining red metal.
They wander the world, hunting down both monsters and sinners alike.
I forget when I wrote this. I was a teen, definitely.
