You declare that Methiant soldiers are to not stop before Felonsein is conquered, but you will stay behind, citing lack of heirs (which is perfectly fine with your courtiers).
1096 AD, Mid-Spring
You receive first report from the 'frontlines': your soldiers crossed into Felonsein territory, and, after sending a small unit of horsemen fleeing westwards, have captured several villages, the local peasantry equally confused and terrified of the invasion.
Next day, there's a lucky find in one of guest chambers!
One of the guest chambers was overdue for renovation, but when the palace servants moved a large wooden wardrobe aside, a small chest fell out from a hiding space behind it. They've given it to the captain of the guard who brought it to you. With a locksmith examining and then opening the box, its contents are revealed.
The box is filled with golden, pearl and glass jewelry adorned with markings of Houlandine dynasty. With an old but still pretty blue-dyed dress included, these must've belonged to a lady from Luathbas' royal family. There are also few bits of perfumed wax, along with several gold coins. All of these coins bear images of the Luathbas Kings, both from Houlandine dynasty and the dynasty before it.
Treasurer's appraisal experts believe that this box must've been hidden during or after the collapse of Luathbas.
The Treasurer of course asks what do you wish to do with this treasure cache.
A) Send it to the Ceodwells, the only true descendants of the Houlandines. They might appreciate our gift.
B) Try to find a good seller for the trinkets. Who knows, it might help our Treasury a bit.
C) Keep it safe; mayhaps we can gift it to our next wife, or maybe to our daughters when they marry.
