Also to give ya some more halo lore. The only reason the Forerunners where able to wipe out the Precursors is because they refused to fight back and allowed themselves to be killed off. Some went dormant some became a powder that later got corrupted and became the flood. Their main traits are. The race is over 100 billions years old (yep these suckers are a lot older then the universe itself) Neural physics they can create objects so strong and dense they are indestructible except for a Halo pulse tuned to the right setting nothing can destroy them. They are Immortal these guys change their race looks and corporal forms like we change coats they can be physical flesh and bone or even non-corporal basically ghosts. If they are killed they can just come back. Creators of life in our Galaxy and an unknown amount of others.

[i]The only way the Forerunners destroyed star roads was through the use of Halo rings. Precursor technology is immune to damage from anything outside of neural physics, which is utilized in the firing of the Halos. Star Wars does not possess knowledge of neural physics, so they have no means of destroying star roads. Always happy to share. Halo has some really amazing lore. [/i]

Halo would have no knowledge of the force. Both worlds would be at a huge surprise to one another's abilities.
