its definitely tower, that's how they alternate... tower, shrine. eg, conquest, shrine, eg, tower... shrine might alternate between eg too, we'll see...

eg is like a mini event and shrine is a perpetual event (since you can store up to 9,999, its definitely not only 7 days total)

So unless they add another event type, you can expect it.
