Parallel cannon
Parallel Cannons were powerful weapons of war developed by the Time Lords and were used in the Second War in Heaven against the Enemy.
These weapons fired a point hole towards another part of the universe into the nova of an anti-sun where they allowed the neutrinos from that dimension to pass into the normal. Once the cannon punched a hole through reality, the tear opened like a deluge, with physics working differently there as the neutrinos destroyed anything they encountered. In a stream of right-handed neutrinos, normal matter just simply fell apart due to the underlying principle of quantum shattering. Organic matter lasted a fraction of a second longer before disintegrating. If a parallel beam was left on long enough, it was capable of eating through a world in three hours and using up its atmosphere in nine.
They were considered an antique weapon which the Third Zoners were on the verge of developing before the closure of the war in the Fifth Time Assault. Its primariy advantage was that it avoided the attention of the Enemy. (EDA: The Taking of Planet 5)
