Planet History[edit]

Ilion is a planet or system originally within the Free Worlds League. One of the autonomous worlds within the region described as the "Bolan Thumb" in 2571, Ilion is between Tylarzka and Malazan and vanished from maps during the Second Succession War. [9][11]

The 12th Atrean Dragoons, following their surrender to loyalist troops on Calloway VI in the Marik Civil War in November 3014, withdrew to Ilion V with other disenchanted House Marik troops[19] where it is noted they fought a final battle (against each other or an unspecified third party) before forming the famed Hansen's Roughriders mercenary unit.[20] This would imply the Ilion system to feature at least five planets, and the fifth being the primary habitable world; however, by 3014 Ilion was already long abandoned and not listed on contemporary starmaps.
