Dear lord Gow.Taurus,
It depends whether you are using the Puffin browser/PC and logging into this game whilst your friend joins on the iOS version (Rise of Balur) or not.
If that's the case, make sure both of you use the same game platform. (Either both iOS version namely Stormfall: Rise of Balur or via Puffin browser/PC on Stormfall: Age of War)
If you wish to use iOS, check this forum for Stormfall: Rise of Balur iOS and ask your question there.
If none of this all was the case, please consider contacting the Help Desk or reply here, because I might have misunderstood it.
Good luck!
