could even be a new race of flesh eaters similarr to Radukar , more beastlike, if u check the little ones from the boxed game on the 2 on the base the leg is similar, and the pose even
remember that there will be 1 more hero for each faction already existing, they told us so, and they already show us 2, so maybe just 1 hint from rumours can be 1 model specific instead of multiple hints about a new faction ecc
no because the hands on the flute are nurgling's one , but could be for sure a beastmaster idoneth wb , from the other hints.
And idoneth submit creatures in other ways, not by music ecc
Now that I think it that arm is really really skaven like, could be really some new rat kit
Ooooor a nurgling hanged on a death guard bone deformation, since the hook is more advanced than a "medieval" tool
