[@Nytem4re] about your post, two things. First Beacon is not actually connected to Vale, it's on the other side of a large lake and subsequent cliff. You could come into Vale by boat but then you'd need to catch an airship to Beacon. Secondly Gren, Oswald and Sapphire are about five stories up. Oswald teleported there, Gren can walk on walls and Sapphire climbed a lower building from the second floor and made her way up, I don't think you'd be able to easily scale the building unless you had some related semblance or equipment with as far as your CS indicates you don't.

This is more a side thing since I'm not quite sure about the architecture of Beacon but at four stories presumably a slanted roof, it's possible that you wouldn't be able to see Gren unless he was leaning over the edge of the roof. That ones really up to interpretation though.

Now that I think about it how does Grane know Gren?
