Tera leads the town with her prayers. When Richter Belmont or Maria Renard find her, she has a temporary delusion of them being manifestations of God (an effect most likely due to her prolonged capture). She owns a necklace which brings Red Skeletons to total destruction, rendering them unable to reassemble. In The Dracula X Chronicles, it also destroys Red Skeleton walls.
In Castlevania: The Dracula X Chronicles, Tera will present the player with her necklace (misspelled "Terra's Necklace" in the game) if she's rescued in Stage 3'. This necklace will grant the ability to permanently destroy Red Skeletons.
Along the way, the player will also come across certain walls constructed with Red Skeletons' bones. If they are damaged, they'll crumble to the ground but immediately reform themselves, making further progress impossible. However, with the aid of Tera's Necklace they can be destroyed for good, thus giving access to the rewards they were protecting.
In Rondo of Blood, due to the more anime-style artwork for the game, she's depicted as having teal hair wrapped in a ponytail with a yellow ribbon, as well as expressive brown eyes, and wearing a nun cassock, owing to her occupation.
Her design in The Dracula X Chronicles is relatively the same, although the nun cassock is more stylized and her hair is changed to having medium-sized dark brown hair with gray eyes.
- Tera was probably named after the somewhat tragic antagonist of Bram Stoker's novel The Jewel of Seven Stars, the Egyptian Queen Tera.
