Throne of Lies has stayed somewhat mysterious during production, but now suddenly releasing bursts of in-game media, an official game trailer, new art, a fully-updated Wikia for rules/mechanics, with the front page (at least) translated in over 9 languages.
If you missed the Official Game Trailer, check it out here:
The official Throne of Lies Kickstarter date is set for January 9th, 2017 with a humble goal of only $20k with stretch goals for additional feature unlocks. Imperium42 released a "Kickstarter Pre-Launch Page" with all the info you want to know and more, including some reward tiers, clarifications on rewards, stretch goals, concept art and more.
Throne of Lies is currently highly-rated under the Steam Greenlight concepts page. This page will finally be migrated to an official Greenlight page just before the Kickstarter on January 8th, 2017.
