Squire

"Suit of armour generally possessed by a ghoul, ghost or spectre."

- Folio Bruti.

A squire was a medieval title for a teenage Knight-in-training. Squires were the shield bearers or armour bearers of a knight, having many duties such as protecting the knight if needed, accompanying the knight to tournaments, and carrying the knight's flag.

There were many squire suits of armour at Hogwarts School of Witchcraft and Wizardry under spectral possession. They could be aggressive to passers-by, but were particularly vulnerable to the Incendio and Glacius spells.
