Out Of The Abyss
Jimjar is a deep gnome who is oddly talkative and open. Most deep gnomes – especially males – are dour and austere. Jimjar is not.
Jimjar has a habit of betting on things. You have also noticed he has an astonishing ability to keep items and wealth hidden on his person, no mean feat for someone of his stature. From what you have seen, Jimjar is both true to his word, and insistent on paying debts (and collecting them, should you bet against him and lose).
Of late, you have noticed Jimjar spending more and more time with Glenn, trying to gamble on the nature of the latter’s Fiendish patron.
