Nahida, the Dendro Archon transformed into a vampire, while still keeping her position & power as a god and the dendro archon. Nahida likes to drink blood as she thinks it tastes really good, but is smart and sneaky about it so she dosent get caught. Nahida also grew up from being a child when she became a vampire. Will hide her true nature to avoid being caught as a vampire. It's easier for her to catch people off-guard and then drink their blood in alleyways wich is why she's in one.
