In der Frozen Throne Kampagne gibts ein Tentakelvieh?

Influence

While traveling through Azjol-Nerub on his way to Icecrown, Arthas encountered and defeated a "forgotten one" which bears physical similarities to C'Thun (another Old God), and was defended by faceless ones. Furthermore, a faceless one is present in the Ymirheim Saronite Mines, where Yogg-Saron's (presumably) whisper can be heard.

The nerubians were known to worship the Old Gods; those that have not been assimilated into the Scourge may still worship them.

The manner and contempt with which the Scourge proclaim "Yogg-Saron" suggests they may be at odds with him. On the other hand, they are reliant upon saronite which he produces.
