there were many powerful persons but only few could use their power. we know almost nothing about most of mages. no idea how powerful they were but there were couple archmages on thanedd. mages knew them and yet every single one was shocked what tissaya did with just a single gesture. her power was enourmous.hen was definitely powerful but also so extremely old, even for a powerful mage. i doubt he could fight or even run without risking a heart attack.ciri while powerful was an embodiment of chaos. chaos even "spoke" to her and her powers were always a bit .. unstable. besides she was psychically vulnerable. she easily denied all her powers and decided not to use them ever again. it happened once, it can happen any time again.
heart attack was the cause of his death after all.
