Not to mention it has a presence in realms on other continents as well.
While that is technically true, it's presence on other islands is minor, or negligible. Particularly FEI, where is a tiny little thing. And on BT, it hasn't really gotten much (any?) traction outside Old Grehk.
I wouldn't really consider CoH to be a multi-island region. It's almost a multi-family religion (most specifically of three particular families) that take it wherever they go.
