[quote]Not sure how powerful precursors are tbh.[/quote] Their constructs were immortal, totally impervious to being so much as scratched by anything because the Precursors had perfected the creation of things via neural physics. The only things capable of destroying these were Halos because they targeted specific neurons to eliminate potential Flood hosts. The Precursors used orbital arches to connect whole star systems together, and their Star Roads absolutely shredded the Greater Ark and Omega Halo in seconds (the Greater Ark was MUCH bigger than the Lesser Ark because it pumped out Halos that were 30,000 kilometres in diameter as opposed to the ones we see in the games which are only 10,000km in diameter in comparison). Basically, a single Star Road from the Precursors could wipe out both universes and not suffer so much as a scratch.
