10 Strangest Worlds In Star Trek

Theta Zeta only received its name in the script for the end of Discovery's third season, so most will know it simply as the Dilithium planet at the centre of the Burn. Located in the Verubin Nebula, it was the crash site for the KSF Khi'eth, a Kelpian ship on which Dr. Issa served.

She gave birth to her son Su'Kal in the ruins of her ship and then, knowing that she would soon die, built a holographic world for him to play in and be occupied. 

Su'Kal was born on a world with various types of radiation, all of which combined to start warping his genes. He connected with the planet, and through it, the dilithium. It unfortunately acted like a resonace chamber, amplifying his own grief when his mother died. He screamed in agony and in his pain he inadvertently ended thousands of lives.

The force that spread out from Theta Zeta caused every active warp core to breach in that moment, crippling much of the quadrant and reducing Starfleet to rudimentary forms of transport. It took over a century for that crucial part of the puzzle to come to light and to also remove Su'kal from the planet, for fear that another Burn would occur.

It may have been a grand tragedy but Theta Zeta is still an interesting world in a galaxy full of them.
