Almedae are slender humanoids who were the original inhabitants of Castor. The Almedae became known to the Orion Arm peoples on June 1st, 3002, when the colony ship Sai Ranon and its fleet of warships entered Castor orbit. The Almedae and their leader Lady Mellilah Ranon blockaded Castor and announced an ultimatum: the Castori must vacate the world or be forcibly removed. The Almedae never took up the settlement area offered by the treaty. Instead, the Sai Ranon was hurredly patched up, and they made a hasty, although very quiet, departure out of the Orion Arm.
