Meaning, there is no mechanic regarding the fact that a character NEEDS food. As for the fact that grub exists and you can catch something from it, practically nothing was said.
And the second part was an unfortunate phrasing. The Mage Guild and the player see the game differently. From my point of view, there really was no effect from the snack. I didn't lie. But I didn't tell the truth either, because there was a planned event for Aristarkh to get poisoned. The event seemed extremely insignificant to me, so I didn't flesh it out. It was done half-heartedly. According to your words, it turns out that I deliberately lied to you in response to your brilliant question asked straight to the GM about whether there would be something or not. By the way, the question was stupid, because a GM should tell a player to go fly a kite in such a case, rather than answer. But I messed up. A fatal mess-up. And why am I a human and not a machine?
