Your wife gives birth! Your third son is named 'Llewyn' by her.
848 AD, Summer
While fixing some old framework in the basements of your palace, the craftsmen found a hidden stash! There were boxes of clothes and some copper jewellry, and also a large green gemstone. Copper wasn't used for royal jewellery for over five centuries, and the palatial priest determined that the stash wasn't cursed or anything like that.
This treasure stash must've been hidden by some king from 3rd century or so, and then promptly forgotten by everyone.
The Master of Treasury asks you if you have anything on mind about the gemstone.
A) Just add it to our treasury.
B) Commission a craftsmaster to fashion it into a trinket for your beloved wife.
C) Send for dwarves to enchant it into an artifact, as gemstomes (the larger, the better) are best conduits for magic - at least, that's what the folk tales say.
