Here is the next rule from the Code of Conduct, as described in Spell Sweeper, my latest middle-grade novel, with commentary by the main character Cara Moone.
THE SPELL SWEEPER CODE OF CONDUCT
(Do as I say, not as I bespell)
Do not attempt explanation if you are accosted by a Bliss during a purge; summon the local wizard authority.
(“Nothing to see here, folks—this is definitely not dragon egg yolk smeared all over your porch.”)
BTW, Spell Sweepers are not only responsible for cleaning up spell dust left behind when wizards cast spells, but also any other magical . . . er, secretions.
Spell Sweeper is available now in hardbound, digital, and audiobook formats from your favorite outlet.
