You can all see it now: as soon as Zangua says the word "up," a small flame appears over one of the wooden platform's four head-posts. It lasts only for a second, then vanishes.
"So... we can simply command the platform to rise? I recall a sorcerer who once enchanted his entire castle with such nonsense. What was his name? Alexis? Balexa? In any case, perhaps we should board the device and try the command again."
"We guessing there's four words, one for each flame?" Zangua ventures. He steps over to the 'UP' post and inspects it. "Maybe something's on these that'll give us a clue on what the word is."
As Domarc and Mordred speak, two flames appear this time, one over each of the two nearest heads and burning a little brighter, but they too fade quickly.
