A correction, for your original:
They can be jails where criminals have been sentenced to hard time. They can be dark basements, medieval-looking cells or cobwebbed chambers in dusty, dank tombs. They could also be the financial limitations that subject people to indentured servitude.
You go from 'can' to 'could' and it jars abit. I think the last should also have been 'can'
You're right - that could be better suited there. Darn. It's after the 7 day editing time frame hehehehe but as you say - for the original ;)
Thank you @arthur.grafo!!!
