Tim the Kobold

Origins
Tim and the rest of the kobolds of The "Somewhere In Time" Campaign are partially inspired by the Mr. Meeseeks from Rick and Morty, as their main goal is to serve the Eternal by essentially going out to fight poorly and die.

Story
Tim is found near the end of the campaign by the party during a fight with other kobolds, where Tim is on the ground crying. The party spares him, and Tim tells them his name and his story. He was the runt of his litter of kobolds and was constantly mocked by his older brothers for his dislike of conflict. The party decides to take him in, with Rixiron III wanting to teach him discipline, Jack Daniel wanting to teach him how to use weapons properly, and Jazz just wanted to keep him in his backpack.

After the final showdown with Six, the party and Tim go home, only for them to see Tim starting to crumble into dry scales. This is because kobolds were designed to die after a certain amount of time after they leave the cave they were created in, and as such, Tim has reached his limit. When a character attempts to take him out of his misery but misses, Tim's last words are "It's okay friend, I know you'd never hurt me..." before vanishing for good.

However, this is not done (entirely) for shock value; with his death, it represents the death of innocence to counteract the death of Six representing the death of evil. At the end of it all, you can achieve your goal of slaying evil, but at what cost?
