If the encounter is with a boon, and you succeeded at all of the checks required to acquire it, draw it. Otherwise, banish it. In either case, the encounter is over.
If the encounter is with a bane, and you succeeded at all of the checks required to defeat it, it is defeated; if it is not a villain, banish it and the encounter is over. If you did not succeed at all of the checks required to defeat the bane, it is undefeated; if no local character wishes to avenge your encounter (see the Avenge the Encounter section for more details), apply all effects that happen when the bane is undefeated, then shuffle the bane back into its location.
