The ‘Arc of Ascension’ is complete at last with Shadows of the Shroud.

Overhauled Psionic Ascension

Like the other Ascension Paths, Psionic Ascension has now been elevated with an Ascension Situation that explores the impact Ascension has on your Empire. Your moral and ethical decisions will influence your attunement to the domains of the Shroud, culminating in your first delve as you Breach the Shroud.

Track your exploration of the Shroud in the new Shroud Panel, which will show your current attunement to the domains of the Shroud and provide means to influence your spiritual travels. Attuning to a domain grants Accords, and the local Patron may offer you a Covenant: Power for a price.

The Shroud contains 4 Major Patrons, 8 Minor Patrons, and 2 Great Patrons, though not all can be encountered in a single playthrough.

Encounter new events when "Delving" into the Shroud, including 4 new Psionic technologies for ship components.

A new path through the Shroud where you reject Covenants to forge your own way, beholden to no Patron.
