Evocation of Ant'Harratu

I’ve performed the outlined rite on the Book of Azazel to’ evoke Ant’Harratu and the evocati in followed the description of Koetting, smoke start circling and then after few minutes i saw a large figure but not see Him clearly… I’ve issued anyway the task and dismissed Him but. Nothing new happened, i’ve keeped the sigil on my wallet.
Should i use the same sigil or draw a new one?
Someone have already word ed with Him?

I have not worked with Ant’Harratu, but I do know that you are ok to keep using the same sigil (especially since you activated it)

Thank you
