Do we have any idea if Idols will be deleted after the event?

I was able to transfer idols from Phrecia to Settlers by creating a dummy character and migrating it.

But knowing how things went with the Charms (Deleted flat out after the league), Idols might be deleted post-event as well.

I just wanted some clarification. I tried the search function for similar threads but nothing came up for me.

Nothing has been confirmed regarding the Phrecia idols as yet.
