The Godsmen Apocalypse
This dirty human child obviously suffers from a history of malnourishment, and his beady black eyes do not lead one to naturally trust him.
Tiny Tim’s family were shepherds who made a meager living selling wool to a halfling cotton-maker. He was out playing by the beach when the Apocalypse occured, and ran in fear for many days until reaching Mistedge. After meeting the party he led them to his home and discovered the horrifying situation, and then agreed to follow them further. Once combat broke out he ran again and has not been seen since.
