I’m not sure, but during testing I didn’t see direct teleports to individual fortresses.
Would it be possible to make an additional section in GK with a teleport near the fortresses? Fortresses - especially for smaller clans - are quite an important element, especially as the modified residence skills look inviting. The request stems from the fact that you will have to teleport to some of the fortresses via the odd side zone from the regular teleport, which is not very handy.
