So it hath beginneth.

The Vanguard Coterie Infineum Sanctuary Ultimate Quest Guide
begins! We've seen the overview, so now let's get started! We take a look
into rumors that have been going around Ahgram, and we meet Scholar
Donovan, who has a pretty big, yet pretty vague task for us.

Donovan will introduce himself as a member of the Ahgram
Archaeology Society ... He's here to investigate some rumors that there
are some minors collecting infineum in this area. While that may seem like
no big deal, he'll go on to explain that ancient texts talk of a major
even that occured near the area ages ago, and infineum started appearing.
