The Basilisk Universe is a universe similar and related to deceiver. The dimension of time flows slightly faster within the Basilisk Universe, and shared events between it and the Deceiver Universe often happen several hundred (or even thousand) years sooner. Technology and magic are fused with biological life by the time deceiver even happens.

Despite the accelerated expansion of knowledge, ability and time, space travel was never perfected within the Basilisk Universe, as subspace does not exist within it, unlike the Deceiver Universe.
