Jaffie

Jaffie is a member of the Comrades who were the party of the Tomb of Annihilation campaign, being introduced at the door step of Syndra Silvane's house. He was played by Shmexi.
He is a dwarf druid and is known for being fairly wholesome and humble, like an old grandpa. Though also able to turn into vicious animals and ripping his enemies into shreds. He is also the carer and companion of the miniature dragonborn Dave.
During the campaign, he was given the Deck of Many Things by a mysterious old man (Acererak in disguise). When he left, Jaffie picked from it, not knowing what the deck was, picking the card with a dagger on it (rogue). Due to this, it seemed that Barbara, the owner of 'The Inn of the Thundering Lizard', suddenly turned on him and upon Jaffie returning to the inn, she would summon the balor that would ultimately play a major part in the Destruction of Port Nyanzaru. 
During the final session, as he let the rest of the Comrades pick from the deck, he also picked again and got the card 'knight' and thus gained the service of the dwarf knight Reggie, who would follow Jaffie as his faithful companion.
