Starfall. The name seems innocuous enough, yet with hindsight the symbolism within it is as evident as it was no doubt deliberate. Ever has it been that man has sought to hide truths in plain sight though, the better to preserve the lie I suppose.

The events at Ul-Hiyar would would come to have a profound effect upon the Argyntum Stellæ and would play a significant role in the formation of what would become known as the Marines Mendicant but the consequences of the strike against Volnoscere would bear more unexpected fruit in the revival of the Oki-hāmau by the Legion.

Deployed throughout multiple theatres during the Sorrowful Years the Oki-hāmau was less of a formal assembly of dedicated units and more a loose band of ad-hoc formations assembled for specific "hunt/kill" undertakings, with each being led by an Astartes of the Legion. On occasion, this might be a member of the Kapihe though it seems that more frequently, command would fall to less senior officers or line Astartes.

As the parameters of such operations were so varied, it became common for mission leaders to be given significant discretion in their selection of materiel and personnel and as the Sorrowful Years ground on many such individuals came to recognise the benefits of a combined arms approach when assembling their team.

[REDACTED] can be considered broadly representative of an Oki-hāmau formation, and I believe them to have been present at [REDACTED] and [REDACTED], though I have been unable to confirm their presence in this theatre with any veracity and thus the latter of these undertakings should perhaps be attributed to Marines Mendicant operatives instead...
