Families can have their own heirloom pattern, and people in the family that use it get an extra beneficial X from said heirloom; also adds a little bit of RP. The heirloom could be treated like a crest or symbolic representation of being from that family, and it could have utility in metagame. Maybe make it for Great Houses or Banner Houses? Opinions?

Already been suggested, and doesn't need to have any special attributes attached. Simply having a neat crest attached to a unique item should be pretty good on its own.

Oh, I must have missed the thread.
A mod can close it, then.

They don't need to have any special advantages to them, but it'd promote more families to achieve GH.

*poke Prisch* The Talnaras already have a family necklace and ring. Poke Aramel in-game for one.

Oh no way, I didn't realize you already had that done! So fast.
