1) I though about a horn ring, but actually it can be horn anything. Like some piece of jewelry for horns?
2)It doesn't really makes sense to me that he fears the valley so much. I mean, he suffered for so long, he doesn't care about pain anymore, what worse thing can there be that he fears it so much?!
3) Snuggles... But I would enjoy scaring him, then saying I was joking and reassuring that he doesn't have to fear his master.
as for ideas/feedback:
a) Again, it would be cool if we explored more possibilities of the hotel owner. What can he actually do. Why can't he just spawn or substitute artifacts? Why can't he force the hotel to work with new technology? Why he has to walk instead of just creating doors that lead wherever he wants?
b) Why does new owner has to obey old rules? Like, if you set up rules, why can't you change them? What if one of the owners sets a rule that nobody can set up rules? Or at least that you have to whip Asternion once a day, or send him to the valley? Maybe set up a set of ultimate rules, like constitution, and then other rules, that can be amended?
