c´est une quête donnée par lord llethri pour t´attirer ses faaveurs pour te nommer redoran councilor?
moi c´est ce que j´avais fait. J´avais déjà libéré les esclaves au tout début du jeu ( je me souviens plus où j´avais pris la clé...peut être dans la hutte des esclaves elle même), et je suis allé tuer les deux chefs de la mine.
voilà ce que j´ai trouvé sur gamefaqs.com, j´espère que ça t´aidera.
There are two slave shacks in the town, south of the Mining Bunkhouse. You´ll
have to go through the bunkhouse to get to that part of town. Enter Slave
Shack Two. Talk to Dahleena about evidence of corruption and she tells you
about a record book inside the chest on the second floor of the Governor´s Hall
( Caldera). _DO NOT FREE HER_ ( this is very important).
Go back to Caldera. The Governor´s Hall is in the north part of town.
There´re 5 spiral staircases from the entrance hall. Go up the northenmost
one. Enter the first wooden door you see. There is a locked and trapped chest
called Odral Helvi´s Chest. Take the Secret Caldera Ledger inside.
Give this secret ledger to Garisa Llethri ( Ald´ruhn). He tells you that now
you have evidence, you can go and halt the operation of the mine.
Go back to the mining town. Go to the top of the Mining Guard Tower and take
the Caldera Slave Key. Enter Slave Shack Two and talk to Dahleena again. Ask
her about halting the operation ( or similar) and she tells you that she is the
head slave and freeing her will effectively halt the mine´s operation. Free
her. Return to Garisa Llethri and tell him the news.
Reward: Ebony Boots from Garisa Llethri. His support on the council.
Alternative: If you have freed Dahleena already, it is possible to halt the
mines by killing Ordal Helvi ( Governor´s Hall, room next to the one
with the record book) and Stlennios Vibato ( Mining Company Office).
However, you will not be given the ebony boots as Garisa Llethri thinks
your method is undesirable. ( from Luke Jacobs and Tony Patrick)
Also, respawning Dahleena using the console does not work because the
" new" Dahleena does not have the correct dialogue options. ( from Tony
Patrick)
