From the 'Immortals':
"It is believed by some priests that all the gods are but one face; of a greater god. This greater god is worshipped by some priests; who feel choosing sides is unwise or who feel that worship of one; god is better for their personal faith. A few religions have; risen up around the belief in the One God, and it is very popular; in some regions of Elanthia."
From another book 'Origins of the Realms':
"At first was the Void, neither light nor dark, neither full nor empty. Such nothingness as is too dreadful to imagine. Into this Void, came the One who took the Void to wife. From the Void he caused to be conceived offspring, as the she-serpent carried in its body siblings, but all separate and alone behind hard shells, only to bring forth living things that are forever separated and unjoinable. So the One and the Void produced the Planes,
separate realms of world and being divided by irrevocable boundaries of time, space and essential forces.
When she realized that her children were destined by the Father to be ever separate, ever alone and ever full of woe, the Mother Void began to weep. Her tears flowed and flowed, and landing on the Planes, each tear produced a being of great power, born of pure Void. When he saw what his consort had created, the One became enraged, and into each of those eternal beings of pure Void, he imparted some of his own substance, until he had not enough to maintain his own being. With that, he was no more, and the Void, now containing within it a myriad of Planes and Immortals, ceased to exist."
Unfortunately, these are the only "true" mentions of the All-or-One god. From these however, I have put together my (and by default Lennon's) own interpretation of the theology surrounding this perspective. As it is REALLY late for me having just flown 12-hours (yeah yeah my arms re tired), I am not going to even attempt to reproduce it here and now. I may try later if in fact you are interested (but it may be a few days).

Now I lay me down to sleep;
I pray Solomon my soul to keep.
If I should walk before I wake;
I pray that Simutronics a restore will make.
