The tripwires at the top of the stairs behind Jarvia are difficult to disarm in order for a rogue to disable them, switch to 3rd-person top-down view and then move the mouse pointer along the tripwire to either side and into the wall until the disarm icon appears.(If playing as the Dwarf Commoner, Leske will be there as her lieutenant.) When the battle initiates, several Carta Assassins will appear to aid her.

After making it to the heart of the Carta Hideout, you will find Jarvia who initiates another short dialogue scene.(Leske is only imprisoned here if you are not a Dwarf Commoner if that is the case, the would-be Dwarven Commoner Warden's corpse is seen in the other cell)

In addition to this quest, there is a Jail room where you will find the character Leske, who you may free by killing the Jailor and taking his key.

As well as much loot, you may also begin the Jammer's Stash Side-Quest.

There are many rooms and doors with several thugs within and most will have Chests and Barrels with loot in them.

Now you are inside the Carta Hideout and it's time to find Jarvia. It is a sub-quest of A Paragon of Her Kind quest line, obtained after completing Entering Jarvia's Hideout. A Prince's Favor: The Second Task or A Lord's Trust: The Second Task is a main quest in Dragon Age: Origins.
