The following information is taken directly from the Juathuur: Gatecrash cast page:
Serri [sair-ee]
age: who knows
first appearance: 01-12
rank: godly being
A goddess, fourth to awaken. She is Merlu's friend and confidant, but disapproves of his obsession with mortals. Serri is the guardian of the gates, meaning she monitors the traffic between worlds. She often acts as a messenger and go-between when The First is busy. She is also the only god other than The First who has access to the void prison where Lok is held.
Once upon a time, Serri was the main architect of the God's world when it was built, so she more than any other knows it's structure and that of the Gates.
