Official story explainer
Short answer
No. Sons of Sparta is useful Kratos background, not required setup for Laufey.
Why players ask
Sons of Sparta is newer than many older side stories, and it returns to Kratos' Greek-era life with Deimos. That makes it easy to assume it might secretly bridge into Laufey.
What it actually adds
It adds more context to Kratos' youth, his family scars, and the Greek side of his personal history.
What it does not confirm
It does not directly set up the Everywhen, Laufey's awakening after death, or a confirmed bridge into the new story.
Best reading
Read it as backstory if you want more Kratos context. Do not treat it as required homework before Laufey.
