Greed took the mages to the Breach and closed it.
Haven was celebrating the closing of the Breach, with Greed watching over them
He's too cool for such stuff.
(yeah sure *cough*
)
Of course someone had to crash the party. 
Who was it?
An old Tevinter Magister Darkspawn killjoy.
Oh, fun.
That old guy wanted the mark on Greed's hand, but what's Greed's is Greed's and he won't give it back. (so sad there's no "No, it belongs to me now!" answer option
)
Luckily(?) he couldn't get it off Greed's hand.
Hah! Take that. 
Then that old guy pulled the "Archdemon" card out of his sleeve....
CHEATER! 
....
Anyway, after Greed had distracted old, bald and ugly and his pet lizard, so the others could flee, he fired the trebuchet. So that an avalanche would bury the bad guys.
Old McCheat fled with his Dragon of course. 
Greed himself managed to jump into a hole and save himself from the snow that was comming down the mountain.
Finding himself in a frozen cave, he searched his way out, only to find an abandoned cart.
Walking through knee-high snow in a heavy snowstorm he found first a cold and later a still warm fireplace.
After a last look over his shoulder, he took on the last few meters, just to be greeted by his friends.
While Greed was resting on a makeshift bed, the others (Cassandra, Cullen, Josie and Leliana) were arguing about what had happened in Haven and how they should proceed now.
Their bickering was nearly as bad, as that of his siblings.
Both gave im a headache.
Mother Giselle then talked about fate, faith and other Maker stuff.
Ugh.
Greed didn't have time for stuff like that. 
So, while the others started to sing a song, he himself needed some time alone. Which Solas used to take Greed aside and tell him about the Orb, the old guy was using.
According to Solas it was elven and he feared that the others would hold that against his people, but Greed told him that that didn't matter, as long they were still lost in the mountains.
Of course Solas had a solution for that.
Leading them through a mountain path, Solas brought them to an old fortress called Skyhold.
In Skyold, the Advisors and Cassandra has decided that the Inquisition finally needed a leader.
They already had chosen who they wanted as their Inquisitor.
None other than Greed himself.
After some disbelieving looks from Greed, he accepted the job and vowed to stop that old killjoy.
