Maelstorm

A vast plerion nebula swirls around the pulsar PSR J0000+00, also known as Jayzeo, that lies at the center of the Lost Expanse. Neither Jayzeo or the Maelstorm surrounding it are natural in origin, both created by a particularly spectacular example of catastrophic field Manipulation failure on a stellar scale. The precise cause is unknown, but it is believed to have been related to remnants of the Winterdragon Crisis.
The intense radiation streaming from Jayzeo's magnetic poles sweep across the highly ionized plasmas of the nebula at the incredibly precise rate of once every τ/2 seconds, briefly igniting it to a fiery incandescence. Unlike the plerion nebulae previously observed around other pulsars, the Maelstorm has expanded far beyond the shell of gas and dust that forms Jayzeo's supernova remnant, to the point where the planetary nebula is undetectable at all. The fuzziness of its boundaries and the intense radiation make it difficult to determine the precise parameters of the Maelstorm. Current models predict that the plerion is in the shape of biconcave disk approximately 10 Pcs in radius, with a toroidal rim approximately 1 Pcs thick at its greastest cross section. Doppler analysis of the plasma indicates that the plerion is expanding outwards from Jayzeo at approximately 0.32c, and is predicted to envelop the closest star within the next 100 years.
Spectral analysis of the Maelstrom indicates that its composition is extremely anomalous for a supernova remnant. The plerion is an emissive nebula, and the emission spectra indicates that it is comprised almost entirely from the element Lithium, an exceptionally rare element to form in stellar nucleosynthesis. Further, it is strongly implied to be comprised of the extremely rare isotope ⁶Li and by inference its nuclear isomer ^6mLi based upon the emission of radiation at 8.62*10²⁰ Hz.
It is believed that anything enveloped by the plasma vortices of the Maelstorm are destroyed. However, something appears to persist within the plerion's heart. An anomalous radio source close by to the derived position of Jayzeo, but not the pulsar itself, emits seemingly randomly timed radio pulses at the specific harmonic frequencies of 1/τ Hz, 2/τ Hz, 4/τ Hz, 8/τ Hz, 16/τ Hz, 32/τ Hz, 64/τ Hz, and 128/τ Hz.
