QQ: The Druid Island

[Megas Methuselah]

Hey heeeeey!

I remember seeing Duguntz somehow being able to have some of his Germanic family members getting a druidic education on that cool island in mid-western Britain.

So, if someone might be so kind as to answer this: exactly how far does the Druidic education extend in terms of factions? For instance, are Carthaginian family members able to get educated there if they managed to capture it?

Thanks in advance.
