Zelda Zanuba Heap- Is Silas Aunt. She is one of the characters in the Septimus Heap book series by Angie Sage. She is sister to Theo and Benjamin Heap and lives in a cottage on Draggen Island in the Marram Marshes.


She is of medium-build, often wears a tent-like dress (which gives her a dumpy appearance), and has a shock of flyaway grey hair, a wrinkled smiling face, and the bright blue eyes of a White Witch.


Zelda is a White Witch and therefore has considerable knowledge of White Magyk as well as Magyk in general. Throughout the books she has also shown a penchance for Potion making by either making them or maintaining them.

She has absolutely no sense of taste and cooks dishes mainly consisting of cabbages and eel. The only other person who appreciates her cooking is Septimus and Petroc Trelawney.

She has also shown to be a talent in Scrying using The Pond in her garden. She has done so on at least one notable occasion which was when she identified Boy 412 as Septimus Heap


She is sister to Theo and Benjamin Heap and Aunt to Silas although everybody refers to her as Aunt Zelda regardless of their relationship with her. She was the Keeper after completing her apprenticeship to her late predecessor Betty Crackle. The role of Keeper requires them to maintain and regularly visit the Hotep-Ra's Dragon boat who lives under Draggen island, and to escort Queen's and Princesses from the Queen's Way (the exit to which is inside of her cupboard labelled Unstable Potion And Partikular Poison's) to the Dragon Boat during their traditional visit on MidSummer's Day. On stormy nights in the Marram Marshes, Zelda keeps a lookout for any Storm Petrels which might be blown away to the marshes and hopes to meet her brother again one day. There was an instance when a Storm Petrel came to sit on Zelda's roof one stormy night and it wasn't not clear whether it was Theo Heap, although he sat on the roof and said she had always had a talent for seeing the truth in the pond to himself.

She played host to Silas, Jenna, Septimus, Nicko, Marcia and Maxie whilst Jenna was being hunted by the Hunter. She taught them how to create Shield Bugs and altered the Hunter's memory so that he believed he was a clown, in order to stop him from pursuing Jenna. She also captured Merrin Meredith who at the time thought himself to be Septimus Heap, and after being shown in the pond that he was not actually Septimus he escaped only to be Consumed by DomDaniel. Later Zelda Revived Merrin, receiving little gratitude. She tried to tell the Sheild Bugs to act as a temporary guardian until once again, Merrin escaped so he could become apprentice to Darke Wizard Simon Heap.

She played host to Wolf Boy and treated him as a son. She spent her days teaching him in the ways of White Magyk and preparing him to be her apprentice so that he may succeed her as the first male Keeper.
