Which race would you add to Heroes?

Idleness breeds heresy. Eradicate heresy even within your own soul. Thoughts give rise to heresy; heresy gives rise to punishment. It's unlikely this applies to the Griffin Empire, as they don't have such problems. Peasants work – the first point doesn't apply. Paladins strengthen the spirit – the second point doesn't apply. Inquisitors are the main thinkers – the third point doesn't apply. The Griffin Empire is not threatened by heresy. P.S. – These are quotes from W40k.
