This nameless town is the only safe place in the whole game which will work as a shelter for your heroes. Here, you will be able to hire new heroes, healing their afflictions or upgrading their equipment and their skills. From here you will be also able to embark on a new quest and bury those who were not able to retreat alive.
All of the buildings (except for the Graveyard and Town Square) can be upgraded by using the so called Heirlooms which can be found in the dungeons. Most of the buildings have got 2 to 4 upgrade trees which will represent each 'room' of the building. Enhancing these rooms will result with increase the qualities of its services or it will decrease the costs of its usage. E.g. the Tavern. Has got three trees which correspond to the Bar, Gambling and Brothel. Each next upgrade requires more Heirlooms. For now, the buildings can be upgraded up to the sixth level.
The only buildings that are passive are the, Graveyard and Town Square. The first works only as a piece of information which gives you details on your late party members and on their death circumstances. The latter building is present on the Town screen but for now is blocked.
