O’dai Swamp got its nature by being a massive delta formed by the termination of the Rushwhite River. Though abundant in life, it is still difficult to cultivate, being too moist for crops, or even stationary buildings (which tend to sink over time.) Animal life is mostly amphibious, reptilian, or aivan, with only a few specialized mammals roaming its murky depths. Never the type to be deterred by mild difficulties though, the halfling race has found a way to thrive in the swamps, perhaps with the aid of their patron goddess Aururu.
The unstable nature of the swamps make true cities rare, and most halfling ‘towns’ are little more than a particular family line’s boats lashed together. However, there are two cities of note.
