The difference there is, the 'weird creatures' are widely accepted sentient races of Alteiryn and its nearby islands, and further have an invitation allowing them entry. These are guards, at a royal family member's home. If something they are not familiar with suddenly shows up, swords and other weaponry is drawn. As I said, we need to work out exactly WHAT is known by the common people (if anything) about the Hamartians, and then MAYBE we can see about working Zeratul into that particular thread, but it is still at Kchan's discretion considering it is, for all intents and purposes, her thread.
Something I don't do, and have never done, is allow for the 'PC card' to be played. This is less an RPG, more of a cooperative storytelling effort. Yes, you guys are the protagonists, yes you are allowed to be exceptional examples of your races, but you are still bound by the rules of the world. This isn't Final Fantasy or Zelda where you can run into NPC-Jimmy's house and rob him blind and he'll keep spitting the same 2-3 lines at you as if nothing happened. If you are an unusual and mysterious entity, undisguised, people are going to stop, stare, and potentially panic. And then attack. Because that is how most people function. As it stands, Zeratul likely wouldn't have made it INTO Tolvera without stowing away in some form of wagon, because the guards at the gates would have been decidedly put off by his bizarre appearance.
Given the tense air inside the city as a whole, I'd be amazed if some rookie didn't take a potshot at the 'monster'.
Like a relationship, communication is key, and that is what this thread (and the PM system) is for. You want to do stuff, that's understandable, but you need to WORK with us in order for that to happen smoothly and with the most enjoyment for everyone.
