You free the creature of its
chains and it rubs its
wrists and says:

"As a sign of my gratitude I
will tell you a secret, even
though it might not be much
use to you...  In order to
kill Balaan you will need
weapons and armour that bear
a very special emblem."

After the creature has
finished it's story it leaps
aside and pulls a supporting
strut with it.  The gangway
caves in...
