Unbe

I cannot bear my fate as writ, / I'd have my life unbe; Would turn my memory to a blot, / Make every relic of me rot, / My doings be as they were not, / And what they've brought to me!

There is a saying that unseen is as good as unbeen; but in this case it was otherwise—unseen, Master Malrubius was more palpably present than ever before.
