Muddy and murky waters lie under a bridge that seems to go nowhere. It is made of cobblestone and just as long as it is wide. Beneath it live a hideous troll that makes people pay to cross.
Troll's bridge, Swamp
troll
goblin
The goblin lives deep inside of caves far away from the sunlight. The goblin lives on deep cave algae and small critters and bugs that he can catch on the cave floor. The goblin avoids people as much as he can to stay alive.
Why is such a lovely princess down here with you troll? Are you keeping her captive?  No! What makes you think that? She is so gorgeous, and well, you are quite hideous. No offense.  No offense? Leave here if you intend to be so rude, or I might snap. But I see no end insight, the cobblestones seem to lead nowhere! Well whatever you end up doing, just stay quiet. I can not keep quite, I am sorry, but it is not a goblins way. Is there any algae or small critters I can feed on? I am hungry and have been lost for sometime Well I'm sure you could scrape the walls and find something. Indeed, I probably could. Do you make a good living charging people to cross the bridge? Decent enough, I might as well make some money off of everyone's unconditional hatred for me. Maybe if you weren't so hideous people would like you more. I mean, I could help you, and we could charge people DOUBLE! How can I change my physical appearance? Take a look and you tell me what I can do to change THIS?
