In this case, yes. You'd either be going on an expedition with fellow cultists, or wandering the Ascendant Planes of Arnum.
Material
Consisting of the tangible physical world, most beings are born, live, and die here.
Reflective
The Reflective Plane overlaps the Material Plane and all Ascendant/Descendant Planes. It usually cannot be sensed from the Material Plane - however, those in the Reflective Plane can see into the Material. It is presumed that this is the resting spot for newly departed souls before their travel onwards. Incorporate beings and entities exist here.
Divine
Each Deity holds a divine plane of existence to themselves and their followers - they are essentially smaller versions of the Material Plane, although the rules within each plane may differ from Deity to Deity.
Aether
The Aether Plane is the boundary between all planes - endless, timeless, and void of inhabitants, although bits of wreckage and flotsam can be found. It is presumed that the Aether is where the Deities and all powers originate from.
Ascendant
Ascendant Planes are the planes composed of the domains of the Greater Deities. Very little is known of these planes, and it is presumed that these planes resemble what the Material Plane would be like with each deity Ascendant, leading some to speculate that Malu was Ascendant at some point to shape the Material Plane as it is known.
Descendant
Descendant Planes are the planes composed of the domains of the Lesser Deities. Very little is known of these planes, and it is presumed that these planes resemble what the Material Plane would be like with each deity Ascendant.
