Crake leads the Manumits, the rebels fighting Brencis, and his chain is the longest optional storyline in the game. He is also a romance option, but he won't trust Coen until your Infamy is high.
Crake runs the Manumits, a rebel group trying to break the vrakhiri hold on Vale Sangora. He doesn't open up easily, so expect to earn every bit of trust.
His chain starts after the prologue with The Firebrand. Rescue Sara in Shadows in the Woods and she leads you to him. Later quests run through the Rebel's Hideout.
The chain runs through Where Loyalty Lies, What Hunts the Night, What Moves the Dead and Who Pulls the Strings. Optional Distant Shadows and A Closer Look dig into his past, and it ends with the assault in Rise at Dawn and Fall Before Dusk.
Crake's real name is Marat, which you learn after walking him back to the hideout in What Moves the Dead. Ascar, the man you tail in Distant Shadows, is his estranged father. Choosing "Kiss him back" in A Closer Look completes the romance.
You can face Brencis with Crake at your side. Doing so earns the hidden achievement The Knyazmaker.
A Closer LookA Closer Look is the Crake questline step where you go after Marat once Distant Shadows ends badly. It is short, but it carries the bronze trophy The Manumit if you pick the right lines.
Distant ShadowsDistant Shadows is a Crake quest where Coen meets Crake at the rebels' hideout and tails Ascar through Tantari by day. Getting spotted gives a worse outcome, so take it slow and hide behind cover.
Fall Before DuskFall Before Dusk is the ending quest of Crake's questline, a rebel assault on Greifberg Castle that ends with Brencis. Beat him for The Knyazmaker, or bargain with him for The Turncoat.
Rise at DawnRise at Dawn is the ending quest for Crake's questline, where you march on Brencis's castle with the manumit rebels. Save before you start it, because it fails every quest you have not finished.
Where Loyalty LiesWhere Loyalty Lies is a Crake questline quest in Svartrau City where Coen finally gets in with the manumit rebels. You need a high Infamy before it starts, so plan some court activities first.
Who Pulls the StringsWho Pulls the Strings is a late Crake questline quest where you raid a gargoyle-guarded tower for a book. It pays 1000 XP and the Life Lock hex, and finishing it opens the road to Crake's ending.

Marat leads the Manumits, the rebels fighting the vrakhiri. He is brave and well liked but trusts almost no one, so Coen has to prove himself before the rebels let him in.
Drogos
Drogos is one of Crake's lieutenants in the Manumits, alongside Sara. He is around when you first meet the rebels, and he points you to Crake after the Ascar business in Distant Shadows.

Brencis is the vampire Knyaz who seized Vale Sangora two years before the story, and the main villain. He is the one who tries and fails to turn Coen, and you have 30 days to beat him to your family.
Ascar
Ascar is a beekeeper who lives in a hut on the south side of Tantari. Crake has you tail him in the optional quest Distant Shadows, and what you find out explains a lot about Crake.
