|An Idanian male|
|Arissa, an Idanian female|
The Idanians were a secretive humanoid race. Both male and female Idanians normally wore a cowl over their heads.
During the 2370s, the Idanian government took a particular interest in a member of the Orion Syndicate named Draim, who operated from the planet Finnea Prime. In 2371 they sent an intelligence operative named Arissa into his organization, who, for two years collected information on Draim so as to potentially cripple his entire organization.
