Endora

A real witch's witch, Endora (you can't pronounce her last name) is the major influence in Samantha's life.  Although she always means well in the end, Endora manages to keep poor Durwood's life in utter chaos. 

Family is very important to her and she will do anything in her (considerable) power for Samantha and the children (Darwin is often just an afterthought...if that).  In Endora's world, Mamma knows best...about everything.

Although she is currently separated from her husband, Maurice, they are still very much involved in each other's life.  Maurice is the only one that Endora acknowledges as superior to her...well, maybe, grudgingly, the Witches Counsel...but that's it.

Her sister, Minerva, has recently returned from an extended tour of the universe (following the unfortunate demise of her husband, Maurice's brother)...how else did you expect that Samantha and Serena were identical cousins?  Minerva has recently been seen in the company of her former brother-in-law...much to Endora's surprise!!
