Broken Chains

When an Eagle Knight goes missing while investigating an underground slave operation beneath the dilapidated Twilight Gate district, it’s up to the PCs to delve an abandoned (but hardly uninhabited) qanat beneath Katapesh and discover her dire fate. Yet not everything is as it seems in the dank slave caverns under Twilight Gate, and clues hint that the slavers may have even more loathsome connections than initially suspected. Can the PCs recover the missing Eagle Knight before her fate is sealed? Or will the monstrous slavers lairing under Katapesh succeed in their malevolent designs?
