Everywhere I look for help in uniting the Geth and the Quarians, I only see Legion's Mission in Mass Effect 3 only referred to as just that: Legion's Mission in Mass Effect 3.
Even here: How do I establish peace between the Geth and the Quarians?
And here: Brokering peace between quarian and geth options don't appear
...it is only cryptically referred to as "Legion's Mission in Mass Effect 3." There is no indication as to the actual name of the quest, when I receive it, and what prequisites there are, if any.
