Celestial Orrery

'The Celestial Orrery draws its information and connection through quantum entanglement,' Ashenti argued. 'Were the masterwork destroyed, it is unclear how the galaxy would be affected. There is no reason to think the cataclysm would begin here on Thanatos or even in Oruscar space. In the past, when we have used its powers, the results often caused… unexpected chains of events.'
…
'Fools. Have you forgotten yourselves? Would you unleash arcane energies this close to the Orrery? Even with its shielding we cannot risk destabilising it.'
Trazyn stepped sideways, to peer around the cryptek weapons. 'She seems wise, colleagues! I suggest you listen to–'
'Lower your voice, thief,' she hissed back. 'A shout here could make stars gutter like oil lamps in a wind.'
…
'Was it not enough to try and steal the Celestial Orrery once? It is a perfect, entangled model of the galactic spiral, lord of Solemnace. The merest shift of the matrix, a micron of difference, can cause sympathetic disasters, supernovae, the unmaking of matter–'
…
'It would be a pity, though,' Trazyn said, opening a dimensional pocket and withdrawing a void-black cube. 'For if you fire, I will be forced to activate this. And, trust me, venerable colleagues, you will not like what is inside.'
'You would hold the entire galaxy hostage?' Ashenti sneered. Poison light spilled forge-blue from his ribcage. 'It is stunning in its selfishness. Every being in the cosmos is protected by our vigil. Even one as loathsome as you, Trazyn. Would you see your precious gallery immolated?'
