Hearth of Britannia: Potion Bottles, More Clues

Rustic Dragon has revealed the contents of the previously-opened box set atop the table in the footer of the Hearth of Britannia website: potions!

Specifically, there’s are red (cure poison), yellow (healing), black (invisibility), and blue (sleep) potions on the table now. I am not sure what this implies about the event that Rustic Dragon is throwing, but anything that necessitates the use of a red potion makes me wary.

(And it just occurred to me that cooks in Britannia could make use of black potions in their recipes. A few drops in the soup, for example, to ensure that the broth appears to just spontaneously pop into the bowl as it is served to a customer! But I digress…)

Additionally, Rustic has added another entry to the “Prizes” list, comprising (again) eleven characters: “?????? ?????”. The previous eleven-character string, in the “Activities” column, has been updated slightly: “?????? ??E??”.

One wonders what it could be? And are the activity and the prize one and the same? Is Rustic Dragon planning to speed-run (and give away a copy) of ULTIMA SEVEN?
