Undiscovered Titles

A while back, I was copying some titles from recent patch pages on the wiki and there were a handful of titles added that I never found out what quest they were associated with. I believe they spread out over multiple patches:

Brought to Light
Cathedrals Champion
Creature of Chaos
Lord of Dark Dreams
Master of the Twisted Word
Tactical Fantastical - I assume this is beating the Tactical Defense a certain # of times?
The Dark Dreamwalker
The Dreamslayer
The Nightmare Lord
The Nightmare Mage - I know Count Orlock was just awarded this during a Live Event on DT, but it was added a while back...
The Nightmare Stalker
The Restless
The Thought Spiral
The Tou Tou Terror - Wiki says the Shadow Invasion quests, but what triggers it?
The Twisted Weaver

Any help would be appreciated.
