The genre drama will return with a shortened season in January along with 'The New Celebrity Apprentice' and 'Emerald City.'

It's the end of the road for NBC's Grimm.

The network announced Monday that the forthcoming sixth season of the genre drama will be its last.

Set to premiere Friday, Jan. 6, at 8 p.m. ET/PT, the final season will feature its shortest order to date and consist of 13 episodes (each of its previous five seasons had consisted of a full 22). NBC buried the announcement in a release touting the midseason premiere dates for Grimm, Emerald City (Jan. 6 at 9 p.m.) and The New Celebrity Apprentice (Monday, Jan. 2, at 8 p.m.) The network touted that the final 13 episodes will see the long-awaited battle between Nick and Capt. Renard.

Produced in-house by Universal Television and Sean Hayes' studio-based Hazy Mills banner, season five of the fairytale entry averaged a 1.7 rating among the advertiser-coveted adults 18-49 demo and 6.4 million viewers when factoring in seven days of DVR. The drama is one of the most time-shifted on broadcast, improving by an average of 90 percent in the demo and adding more than 2.4 million viewers overall.
