To all participants, thank you once again for your wisdom and patience.
If I am now stretching things too far by committing thread-romancy, please simply ignore this post, along with my apologies.
I have made two changes on which your evaluation would be appreciated. I have altered the lineage of the Oath Keepers to stem from the Angels of Absolution. This way (perhaps) the sequence of events become somewhat more plausible.
Along with this, if the Oath Keepers are not to be completely destroyed (I am still undecided on this), here is an ending that tries to make it possible without an unrealistically neat solution that resolves all conflict.
A small crew of surviving Oath Keepers, less than 200, had escaped the ruin aboard a damaged sword class Frigate. They arrived on their nearest recruitment world (Redemption Secundus), to discover that forces from the Angels of Vengeance were waiting, having tracked them through psychic means. The future of the chapter is unknown. Doubtless, the Angels have received a full report of the chapter's history. Only a single member of the Oath Keepers' Inner Circle had survived to explain the order's choices. Understandably, the Angels of Vengeance were deeply suspicious. On the one hand, they suspected that the Oath Keepers may have been manipulated by the Fallen. On the other hand, even if their story was true, the Oath Keepers constituted a dire risk to the secrecy of the Unforgiven. The Angels of Vengeance were in a superior position, for they still held all the relics, equipment and gene-seed of the Oath Keepers. Their Chaplains interviewed all the surviving brothers separately, hunting for the truth. Since all these Astartes bore no knowledge of events on Caliban, they could not fathom the suspicion and hostility of their gene-brothers.
At some point during the deliberations, elements from the Angels of Absolution arrived. Once they had been appraised of all that had happened, the delegation stepped to the fore, to speak on behalf of their successors. The Angels of Absolution announced that they should take ultimate responsibility for the actions of the Oath Keepers, claiming that their original teachings may have inclined the Keepers to abandon the Hunt. Although barely a feasible argument, it was designed to allow a compromise. Claiming ultimate guilt, the Angels of Absolution proposed to the Angels of Vengeance that they would oversee the rebuilding of the chapter. Moreover, they would insist that from that day onward, a Chaplain from the Angels of Absolution would accompany every task force of the Oath Keepers. Each Chaplain would watch for signs of corruption and treachery.
Eventually, it was determined that the Rock should announce the final judgment. Whether the Oath Keepers will be allowed to rebuild has yet to be decided.
Never mind... my apologies. I think its best if they no longer exist.
