A rare but cherished occurrence, the Calf Communion ceremony celebrates life and birth among both the tulkun and the reef Na’vi. Held at the Ranteng Utralti (Na’vi: Spirit Tree) in the Cove of the Ancestors, the Na’vi and tulkun gather for their young’s first communion with Eywa. This first communion with Eywa is a moment of deep significance and celebration among both peoples. However, the gathering of tulkun quickly draws the attention of the RDA as a target for a massive tulkun hunting operation to easily secure vast quantities of amrita in a short amount of time.
