Editing Spelljammer Helm (section)

=Crystal Throne=
Used by and only by the [[Thri-kreen]], a huge, multifaceted crystal, about 8' high and 4' wide in the shape of a wide-armed throne that glows a pale light. Its workings are never explained, but we do know that the throne doesn't need to be feed spell slots and the Ship's Rating is determined by the quality of the Throne itself instead of the helmsmen.

Only the thri-kreen have the right faculties use the Throne, and its likely a helm designed to be powered by thri-kreen innate psionic powers instead of being of [[Arcane]] design.
