Does anybody know?

I want to return to POE1 to get my The Autumn Knight Armour set. However, I am wondering if the character I join must be in the Setter's league, or can it be in the standard (parent) league? I didn't play the Settler's league so I have to start from scratch, which is gonna be a lot harder than starting in standard league where I have many old items I can use.

Does any of you know? Thanks!

You have to start from stratch in Legacy of Phrecia event, not in common Settlers.
