Jen is a creature with the ability to grant people's deepest desires, and will give you cruel costs to achieve them as he manipulates and allures you in with your own wants and needs. He uses people who come to him looking for things for entertainment, and if they don't follow through with their deal, or bore him, he has been known to send his roots after them.

Jen is not entirely gone from reality, and has shown genuine moments of kindness to others and their desperate pleas. Jen can take pity on others and has on many occasions gone out of his way to bend the rules for those he does not deem selfish. Jen raised a boy in Cinnamon and trained him to be a responsible and reasonable thinking young man, if not passing on his own anti-social behavior to him as a downside. Jen is relatively reclusive and introverted, disliking people entering his forest in general, and this became most apparent after he lost his close friend Cumin, who died in his forest when she got too close to him during a violent hallucinatory outburst.
