Ironwood was the partner of Moonhunter of the Red Fern. Given Moonhunter is assumed to be male (as his children inherited the name 'of the Red Fern'), Ironwood can assumed to be female and the mother of Starlight and Swiftbrook. It is not known, but very likely, that Ironwood was a lamia.
- Ironwood refers to many species of tree whose wood is known for its great hardiness and strength. Thus, Ironwood's name is a typical lamia one. Ironwood is also one of the few lamia shown to have a name associated with trees, which are considered special names for the lamia.
- Interestingly, Ironwood's name contains the two substances that are deadly to two species of Night People - wood is toxic to both kinds of vampire, whilst witches have a severe allergy to iron.
