After Agapios broke up with Dione at the beginning of round 11, Lysander, Dione and their daughter Amanda got their own household. (Even though Dione wasn’t in love with Lysander, but she had nowhere else to go.) Since the Obsidian household got way too crowded after Penelope gave birth to quads in round 10, Lysander’s sister Victoria and her children with Odoac, Eusebio and Kallisto, moved in as well.
In round 11, the Water household unlocked Ra, their parrot. Sidonius became an adult, Kay and Saoul became teens and Ragnar and Oberon had their toddler and child birthdays. Samael sadly died of old age, which means Eudora is the only surviving founder.
