Hornbeam selects for its life mate the talented witch or wizard with a single, pure passion, which some might call obsession (though I prefer the term ‘vision’), which will almost always be realised. Hornbeam wands adapt more quickly than almost any other to their owner’s style of magic, and will become so personalised, so quickly, that other people will find them extremely difficult to use even for the most simple of spells. Hornbeam wands likewise absorb their owner’s code of honour, whatever that might be, and will refuse to perform acts – whether for good or ill – that do not tally with their master’s principles. A particularly fine-tuned and sentient wand.
