An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger, but after targets have been chosen for that spell. It resolves even if that spell is countered.

Because it’s not on the battlefield yet, casting Sigil of the Empty Throne won’t cause its own ability to trigger.
