The City and the Tentacle

Forest had swallowed the city, and plants had replaced the buildings. Human, the wisest of all creatures, built a splendid civilization with flames and steel, but it only took nature some time to get rid of it—even devour and assimilate it all to become part of nature.

The civilization on this planet had gone for a long time, which was evident from the sad state of the ruins. Buildings had not only collapsed but also become the nests and territories of wild animals. The human builders had carefully designed these things to showcase their knowledge and strength, but in the end, wild animals were the ultimate beneficiaries of this human legacy. These 'tenants' apparently did not care what the original functions of their lairs were.
