Jardak's Home is the home of the human fighter Jardak. It's in a group of houses located behind the Ducal Palace, between the Temple of Helm and a generic house, in the district of North Baldur's Gate. The front door is locked(30).
On the ground floor is Jardak's Half-elf servant Drelik. The chest is locked(30) and contains 15 and a Small Shield.
Jardak can be found on the second floor standing in the bedroom near the doorway. Both of the nightstands are empty. The chest is locked(30) and contains a Throwing Dagger and 6 .
Note: Even though all dialogue with Drelik and Jardak leads to fighting, they'll still call the Flaming Fist if they catch you looting either chest.
