Like magic Methnik’s sword passed through that of his foes….All too late, the blade was at his neck, it burnt, stinging like acid, it slivered through skin and muscle. Methnik crumpled to his knees, then to the floor, his eyes greyed over and he heard faint words, maybe those of his foe? "Your last lesson in this life. Your teacher? A Serivemn"
‘To the victor goes the spoils’ it is said but what if those spoils are not what they seem. What if those items of victory, are deadly.
Temple of some malign being invites you warmly and offers help (curing,needed spell etc) for some minor sacrifice . Sacrifices must be everytime bigger to work - up to living inteligent creatures. Maybe you pay some other price,too...
