Memory moth

The memory moth was a type of moth native to New Holstice. When released, they held a single name that they whispered back. They were also considered immortal. Memory mothes were then released into a giant cylinder where thousands more were held, each one commemorating every Jedi that ever died. Anakin Skywalker used these after the Battle of Jabiim for the deaths of his Padawan and Jedi friends.
