Image of Unknown Cultural Artifact
The T’andoor’ii explorers had not thought it likely they
would encounter any standing structures remaining in the explora-zone, so they
were thrilled when they came across a ruined building that still had an intact
roof.
There was much debate about the purpose of the building,
which was too large to be a single-family dwelling but too small to contain a
whole community. The youngest of the explorers suggested it might be some sort
of house of worship but his-her suggestion was dismissed. From what the
explorers knew of the dead civilization they were studying, it had been a
godless one.
