Iskalonian was the general term for the different aquatic sentientspecies who lived in the oceans of the planetIskalon. All seventeen of these species were relocated from their own homeworlds to Iskalon circa 5,000 BBY.
C. 529 BBY, a number of needy Iskalonian locals were approached by recruiters sent by Hugo Bartyn. Bartyn wanted amphibian fishermen to settle a new city in Lamaredd and tempted these poverty-stricken individuals with promises of untouched seas in a new frontier. Once they arrived, however, they became slave laborers. Most of the Iskalonians refused, and they were banished to an almost-sure death in the open seas.[1]
Though they built the underwater city of Pavillion to interact with water-breathing visitors to Iskalon, it was destroyed in 3 ABY after an Imperial attack set off an enormous tidal wave. Afterwards, the Iskalonians withdrew from the galaxy's affairs. Kiro was an exception to this, as he briefly left his homeworld for several adventures alongside Luke Skywalker.
The Iskalonians continued their isolationist ways, even after a brief invasion by the Nagai was driven off (thanks to Kiro and Skywalker). The Iskalonians did not join the New Republic.
