Is Sidious still alive ?

Thought I will ask as I wasn’t sure with regards to the secrets of the sith I take it it’s canon ? And if so Sids is still alive as he made Mention of it towards the end etc ?

Or was it just fan based ?

God I hope not.

Can get plenty of him in Prequel stuff (which will never end). No need to keep him around in any more sequel stuff.

Oh I'm sure there are some ham-fisted ways to resurrect Palpatine, but for now he's dead.

Tbh, Snoke returning at some point would be more likely.
