A shortage? Are you serious? (endgame dt spoilers)

[CNitsah]

A calamity happens because the aether on a reflection and on the Source becomes so high that the aether from the reflection 'floods' the Source, rejoining the two. Lightning calamity... reflection destroyed by lightning... no connection here?

I'm saying you can have 2 lightning calamities because there are more shards than elements, and since you LITTERALLY go in the shard where Alexandria comes from (12th floor is still in that shard), it means the shard STILL exists, and thus it's probably not the 12th. There is the possibility of time travel to a past where the second calamity didn't happen yet, but if that a possibility, you can make the ascian come back from the past, and still recreate Zordiark with part of him from when he existed. If that's the way they go, nothing matter anymore story wise. So I'm gonna assume they thought a little about it.
