The High Magic Council is filled with those who are capable, through magic, to engender an element. They aren't abstractions themselves so much as they are avatars and actors of that unknowable force they embody.
We have the goat of Life
The H E C K K of dimensions
The Skull of Time-Space
The Rhomb of Stasis
They each embody a universal constant or abstraction through magic.
Glossaryck is just the embodiment of Magic itself. Naturally, in the realm of magic, he is superior to those using magic to embody elements.
Note: how old mate time is not on the council. Not how his very actions affect the universe as opposed to him being able to manipulate the universe through a particular force via magic.
