All in the Family?

Does anyone know why this family symbol only has a date and a star While others have something like a leaf or a flower. Is that still a family or is it something else? Is legendary a family?

New buff for old hotm. Each year’s hotm are now a family. Check the gameplay section for lots of threads explaining

It’s a new family, explained fully in this thread


It is even in the name “legends 2018 family” on a HotM from 2018… not that hard to guess what it means.

The symbol is picked arbitrarily. It could have been anything they like from a skull to a heart.
