Areen was a Kaylar male of the 24th century. He served as an Administrator of the Kaylar workers contracted to provide construction and repair services on Votar VII, a Federation colony world being developed as a joint venture with Rigelians in the 2360s.
In 2368, the Rigelians attempted to renegotiate their contract with the Kaylar laborers and tried to force a lower rate of compensation upon them. Areen and the Kaylar refused the terms of the new contract. In response, Areen led an assault on a dam and a power planet, "repossessing" the facility, and his subordinate Aton switched off power supplies to the colony.
As Votar was a strategically important location to the Federation, Starfleet sent the USS Enterprise-D to mediate the dispute. After early attempts at diplomacy met with resistance from the Kaylar, Lieutenant Worf and Ensign Ro Laren led a non-lethal assault on the Kaylar occupiers, but were fought off by Areen and his men, in which Areen dueled Worf with a sword. However, Areen told Worf that the Kaylar had no intention of destroying that which they'd built
