[X] Significant cultural artifacts which hold no innate value past what a collector might appraise them at will be returned to their point of origin, likely for display in a local museum in the case of Imperial historical articles, or in the case of Sarnor remanded between the cities they trace the most direct point of origin to, to be discussed between those City States you have established contact with as a gesture of good will and cooperation.
[X] Magical items and artifacts found will be remanded into the custody of those who had taken the risk in claiming them, given they have strategic value, with the caveat that those items may be traded for materials or wealth of equal value, pending negotiation, if they have a point of origin for the party in question (past things like sentimental significance, they might be vital for research the polity was conducting before the Doom or be related to magics practiced in the time of legends).
[X] Material wealth (bullion, gems, rare material components and reagents) will be split evenly. More as a gesture of good will than anything else, and the fact that they will need the capital if they wish to fund soul transference on a large scale. [X] Lay specific claim to the body and equipment of the Charnel God & the Rat King as they fell mostly by your own hand. -[X] Negotiate with Queen Namaaru for the bulk corpses of the foes slain in battle to feed to the Forges, though of course her own dead are unquestionably hers.
