It seems that this warehouse in the slums area of the Συνοικία του Ναού has gotten a lot of use through the years.
Στο παιχνίδι The Witcher
The warehouse is where Vincent conducts his little "sting operation" on the local Salamandra he has recently identified. When Γκέραλτ gets out of prison, the captain suggests that the witcher stay way from the warehouse in the slums, especially around midnight. A witcher's sword would not be needed then. Indeed!
The warehouse is also where the mysterious stone that Drevin spoke of is located in A Mysterious Treasure.
