Okay - what is known:
Alekah - granddaughter of Savah, created the Sun Symbol at the Bridge of Destiny.
Almeck - a treeshaper, who created the first Dreamberry bush. When I remember right he sacrificed his life for it - being already very exhausted mentally and physically this creation took all his strength. He did it to give the elves something to remember their past/history - the Dreamberries trigger memory and make the stories keep in mind. (my own memory is wonky, sadly).
Maalvi - one of the founders of Sorrow's End, Hassbet's cousin and probable mate. Not sure whether there was told more in the novelisation.
Creation seems to be a link. Creating something unique/important. Maalvi is a bit of a stretch, but founding a new home and a new folk is creation, too.
Or symbol - the Sun Symbol, the Dreamberry bush as a symbol for memory ... Maalvi?
Just some ideas coming when I wrote down the bit that#s known.
