Comment on Tali'Zorah Vas Normandy by TrepaShikamaru

Yes, you're right ! The dark Matter is a assumption, not confirmed (Rumor who back from Talis Loyalty Quest)... wait and see. Maybe this is explain in the comics "Homeworld", the episode with Tali! In France, it's not arrived again (Like with James Vega also, grrrr !!!).
Now, i wait the new DLC, whoever speaks of a Leviathan, i'm curious to play that. Funny to find this information inside the code of the "Extended Cut"
