My condolences.
I think Cyre is a good one. Doesn't really matter to a soldier that had no prior connection to any side, but I guess Ogham picked up a few cultural quirks, such as firmly believing in the rightful rule of the Cyran monarchy and a sense that everyone else may have been victorious (if it can be called that way), but they were still wrong.
I am finding the Soldier background to be somewhat lacking. Is it alright if I use the Inheritor background (from SCAG) and consider the amulet-shaped druidic seal the inheritance?
