You can talk to the "global unicorn", kind of

[eriktorbjorn]

You can try to order GLOBAL-UNICORN around, though it's not as exciting as it first sounds because whatever command you try to give it, it's interpreted as if you yourself are doing it. (I remember that in the version of Zork III that I played back in the day, if you typed "DUNGEON MASTER, KILL ME WITH THE STAFF" he would actually kill himself. Possibly a related bug.)

To test, go to for instance the Formal Garden:

>UNICORN, DROP SWORD
Unicorn? What unicorn?

Dropped.

To fix this, we have to add a <SETG P-CONT <>> somewhere in GLOBAL-UNICORN-FCN.
