The mc shouldnt worry about lifespan theres a dark elf mage thats thousends of years old whos name ive forgotten so there are magic methods to extend lifespan that on top of his natural lifespan of 2000 years that is going to increase according to the mc thats more than enuf time to figure out how to become ageless or even become god like minomarco
how is he gonna enter the soul cairn you know without dieing also plz let him somehow kill the masters of the soul cairn there is alot of people/souls in the soul cairn that have alot of lost knowledge that could be usefull it might even give + in magnus eyes by remakeing the realm into something like temp place before entering reincarnation like sovenguard
