Marvel has released a new TV spot for the mid-season return of Agents of S.H.I.E.L.D., and it features the first time that we hear the term “Inhuman” used in the Marvel Cinematic Universe. Is this the beginning of the link between Agent’s of S.H.I.E.L.D. and The Inhumans? sounds to us like this link is pretty obvious, the studio is obviously using the series to prep audiences for the full-fledged Inhumans feature film which doesn’t come out until 2018.

The promo is called “Skye Quakes,” and it revolves around the character Skye, whose true identity was revealed as being Daisy Johnson a.k.a. Quake. Marvel’s Agents of S.H.I.E.L.D. is set to return with a Inhuman story arc on Tuesday, March 3rd, 2015.

Vin Diesel has already teases his roele as one of the Inhumans in The Inhumans, read more in this here.

Here’s more info on The Inhumans:

The Inhumans are a race of super powered beings who live in isolation and do not trust humans.

The creation of The Inhumans was apparently twofold — to investigate possible ways of circumventing their own evolutionary stagnation, and to create a powerful mutant race of soldiers for use against the Skrulls. However, although their experiments were successful in creating a strain of humanity with extraordinary abilities, the Kree abandoned their experiment for reasons which are not yet clear.

The Inhumans went on to form a society of their own, which thrived in seclusion from the rest of humanity and developed advanced technology. Experiments with the mutagenic Terrigen Mist gave them various powers, but also caused lasting genetic damage and deformities. This led to a long-term selective breeding program to try to mitigate the effects of these mutations. Their city Attilan has frequently been relocated and, as of 2005 stories, rests in the oxygen-bearing Blue Area of the Moon.
