Yurian

The aldani, also known as yurians, or lobster men, were a race of crustacean beings that inhabited in the rivers of Chult in southwest Faerûn.

Description
An aldani resembled a lobster the size of a human being, walking on two humanoid legs but they could swim like lobsters. Its face was also similar to that of a human, though encased in chitinous armor and with eyes on stalks.

Ecology
Despite a heavily armored appearance, aldani were quite intelligent and very civilized, with a society. Disputes between them were resolved with courtly tournaments, though these were usually to the death. However, outsiders who fell afoul of the aldani were rarely offered the option of a tournament battle. Many yurians made their homes in the caverns surrounding the Snout of Omgar.

Society
Communities of up to twenty aldani lived at the murky bottoms of the largest rivers in Chult, namely the Olung, the Soshenstar, and the Tath. They never left the water, so few outsiders saw them outside this environment. They claimed a very specific section of the river as their territory, and patrolled it strictly. Aldani patrols could be accompanied by up to twenty trained piranha.

History
Around 1363 DR, Mainu of Mezro, a bara, dwelt in the Olung river with a dozen aldani guards in her throne room.
