[Fate]

Two construction 8 items could help here:

Boots of the Planes (3S? 4S?) allow the commander to Teleport, but horror mark and drive them insane (along with possibly zipping them off to the void?). They do give them a bonus towards escaping the void, but that hardly matters after they have gone insane from being there for more than a turn.

Gateway Stone (2E4S? I think) allows the commander to cast Gateway. I don't think (?) it has any side effects.
