A flickering gateway to a bazaar
Aside from the vendors who've set up their stores at various places in the 
dungeon, there are others trying to make a living by traveling from place 
to place. Bazaars feature a number of different shops and often have better 
stock than the sedentary ones, sometimes even at a bargain. 
Once you hear the clinking of coins, be sure to hurry up and find the 
impromptu marketplace before the caravan moves on!
Also be warned that their nomadic lifestyle has taught these sellers to 
appropriate any items an adventurer might leave behind, and then leave 
quickly, probably to sell them elsewhere.

A frozen archway
A permanent cold front seems to surround this portal. Whatever lives on the
other side, they will be full of grim and arctic fury. You note that the
archway is melting away.

A glowing drain
Every settlement brings forth the unpleasant sewers and drains, ignored by
most but hideaways for others. Old tales speak of dangerous creatures,
bathing in disgustingly green water, preying on each other without mercy.
The tales also tell of the valuable items left by daring and unfortunate
visitors, left to collect dust in the damp caverns. You have an uncanny
feeling that the drain will fall apart rather soon.
