Father of the Oak, Sylvanas, also known as the Father of the Forest, Father of Verdancy, God of Wilderness Nature... The name is not important; what's important is that Sylvanas is a deity with formidable divine power.
All things related to nature could be said to fall within the scope of Sylvanas's deity position, and the Druids who revere nature naturally worship this deity.
Sylvanas has many allies, such as Goddess Shanteya, Lord of the Dawn Rosanda, and so on, which shows how powerful this deity is. However, despite having many allies, Sylvanas has not established his own deity faction, and it seems taking on a Lesser God might be a first.
"Lady of Mist, what exactly is going on?" Amberser asked curiously.
