: I was thinking that the lava that seemed so ubiquitous in some levels of
: Marathon 1 wasn't really lava at all. Many astronomers believe that Deimos
: was just a large asteroid that got pulled into Mars' orbit. Either way,
: Deimos is pretty much solid rock, and would have no lava. Since this is
: the case, I can't think of any good reason for the UESC to pump the
: Marathon full of lava (though maybe this was done by the same UESC
: engineer who came up with the rising platforms in Colony Ship For
: Sale...). So my alternate theory is that the lava is actually molten slag
: from a manufacturing plant of some sort. Its quite possible that a lot of
: materials used by the Tau Ceti colony would first be manufactured on the
: Marathon, and the slag could be a result of that. Any other ideas?
Deimos is too small and old a planetary body to still have a molten core. In trying to explain lava on the Marathon to myself I have become quite an apologist for Bungie. It could be rock or metal or both and therefore be:
some kind of engine coolant,
manufacturing processing,
molten byproducts of other processes used as security barriers,
a byproduct of new tunneling,
large scale spaceship-stabilization/weight-distribution system,
or they just thought it would be super cool to have a bunch of molten rock laying around like the other spaceships have.
