Your Weird is to go to the Place of the Dammed, to seek there the device of those who would harness Helios and to discover from it their True Number, that can allow you issue them The Call.
The Psi of their number is digits four then three, as read by the Talmudic scholars. The Omega is digits two then one, in the same tradition.
Take you then their Omega and, subtracting the One, multiply it by their Psi to find what thousandth minute fraction beyond the pure current degree you must travel toward the rising Sun.
Take you again their Omega and add to it the first of the perfect numbers, then again multiply it by their Psi. You have now the fraction beyond the 48th beyond the 33rd degree that you must seek.
At that point, the contents of your mystic scroll will become clear to you, have you wit enough...
Be warned that a warlock, when found in his den, will still have magic to cover his escape!
