I ran the Enchanter Trilogy games through txd a while back, and I found some interesting actions in the Spellbreaker code.
#rand [number] seeds the RNG, as in Enchanter.
#comm, #reco, and #unre are like Inform’s record and replay.
$xe [noun] appears to be a spell of some sort. Attempting to cast it says “You don’t have the original memorized!”. “original” is in the game’s dictionary, referring to an object with spell-like properties that begins the game out of play. I thought it might be the “spell” written on the blank scroll, but “gnusto vellum”, “gnusto $xe”, and “gnusto original” all fail while I’m holding it. Any thoughts?
