The Guardian

The Guardian regards the quintet of unicorns with what you suspect is curiosity, although its attempt to pet one of the unicorns succeeds only in scaring the woodland creature off. After this, the Guardian waits patiently by itself until Azrien blasts the hole in the ceiling.
After surveying the once-sealed room a final time, the Guardian moves to stand close to the rest of the party, hovering almost protectively over Azrien while everyone floats up and out.
