I assume you mean chapter 2 the part where Meleiss arrives and rescues Jon? Well, let's say that her magic has certain effects that will be better described in later chapters. I don't know what beacon you are referring to. If you are referring to the portal that she opened to go with Jon, I don't want to advance anything but I guarantee that it will be seen in the next chapter. As for why Meleiss is like that, let's say that this is her personality, which for me is something normal after what happened in the first part of the prologue. I mean her adoptive parents were eaten as well as her brother. And I don't want to advance anything but something came in her comfort.If you were not convinced by this answer, please be a little more specific and tell me what part you do not understand to explain better.
