Moss was born from Zarya and an Arcane dragon from a friend lair. When he was still an hatchling growing up in the Everbloom Gardens his green eyes and his peculiar colours, along with his strong connection with the mother Gladekeeper made him become the clan's Oracle. Growing up he became the gardener, but dragons keep going to him when they feel the need to connect with the Nature Goddess.
He's constantly absorbed in his thoughts and prefers spending his time in the garden, alone. His mother Zarya doesn't completelly understand his choices and even if they're living in the same lair, they're not really close.
