When is it time

When is it time to move on and enlist the help of another dark lord? My request was made to Lord Rosier around 5 weeks ago, and I havent had any signs, I have tried very hard not to think about it, and have filled my thoughts with other things.
Right now Im thinking of approaching Dantalion, but I dont want to upset Lord Rosier! I think I may call him one more time and ask if he can give me the answer in my dream! And if he cant or he is not willing to then can he suggest another Dark Lord

I suggest you do a divination instead. If you don’t get anything from a few divinations then perhaps proceed
