When their humans left, the houses were left to fend for themselves. Most sank into a state perhaps analogous to a coma, uncaring of what became of them or of what wildlife nested in their eaves.
Some houses attempted to attract or entrap more residents. These were for the most part easily avoided. Mourning dove carcasses would pile up inside the front door, and any explorer who ignored a large stack of dead birds was considered to deserve whatever happened to them.
A few, enraged at their abandonment, became frankly dangerous and had to be burned. In those cases, even the remains of foundations were believed have an unpleasant effect upon the sensitive.
