This won't be the last you hear of him, but I'm a sucker for Sangheili theories.

I thought of something after reading Manuel Bothelo's take on Gravemind (October 17). Manuel suggests that Gravemind was made out of flood-infected forerunners. One panel in the Art of Halo shows Gravemind with Sangheili(Elite) skulls for teeth.
Manuel's theory- Gravemind is made of infected forerunner
Art of Halo- Gravemind is made of infected elites (Among other things)
If the Elite part of Gravemind came from Regret's honor guards, he must have assimilated them unbelievably fast. Regret's corpse is practically untouched apart from being reanimated, so the Elite corpses should logically be in the same state. The only other explanation is that the Elite skulls came from Elites that had been on the ring well before Regret. Tie that in with the aforementioned infected forerunner theory, and what do we get? Elites were part of the Forerunner, maybe in the same sense as they are( perhaps more appropriately were) part of the Covenant.
