History
The Helion Legion was raised to supply Astartes forces to the further-flung worlds of the Imperium. It is currently defending the isolated Industrial World Arkalli against Orks and Plague Marines. The Chapter is cut off from supply for long periods.
Notes
Short of power armour and recruits, hence many Scouts. Terminator suits usually keep one panel in the old Ultramarines colours; instead of the Chapter badge they show a roll-call of previous wearers.
