Unusual Matierial on Weyland Site

Hey gang...don't know if anyone had mentioned it before...apologies in advance if so but, on the Weyland Site on the Investor Information link there is a list of Earth Resources. Most of the list is unremarkable but, I noticed a handful of materials there that are fictional. Adamantine, Carmot, Eitr, Orichalcum, and Tridium are the ones I'm talking about. Adamantine is a very hard metal/material. Carmot is also known as Philosopher's Stone. Orichalcum is a metal of Atlantean origin, second in value only to gold. Tridium - no hits on searches on this spelling. Eitr is the most interesting in relation to Prometheus as it is described as the "substance from which all life springs" according to Norse mythology. Additionally this substance is described as "supposed to be very poisonous and is also produced by Jörmungandr (the Midgard serpent) and other serpents". Since the storyline of Prometheus seems to deal with our origins it's especially interesting to see it mentioned. The reference to poison and serpents is another interesting possible tie in with the plot. Don't know if these will play a role in the story but thought it interesting they showed up on the Weyland site. Cheers!
