Wow, at first I passed this off as rampant theorizing but going back to read the chapter....
"No, no stories, friend," Grump said. "We want only the truth."
"We'll I've given it to you."
"You swear it by Nu Ralik, that god of yours?"
"Hush!" Ishikk said. "Don't say his name. Are you idiots?"
Grump frowned. "But he is your god. Understand? Is his name holy? Not to be spoken?"
Now, let me write that passage again, with the common words translated to Dula.
"No, no stories, sule," Grump said. "We want only the truth."
"We'll I've given it to you."
"You swear it by Nu Ralik, that god of yours?"
"Hush!" Ishikk said. "Don't say his name. Are you idiots?"
Grump frowned. "But he is your god. Kolo? Is his name holy? Not to be spoken?"
When taken in translation, that DOES sound a lot like Galladon doesn't it?
Not to mention that their names are given ad Vao and Temoo... Not to creative if it's Raoden considering his last disguise name was "Kaloo"
Interesting theory to say the least...
