So I went to the temple of death and burned Cassandra's remains but I don't what to do next

She is top of the phantom forest up a hill trailed with blood, if burned her body go and kill her now she is no longer immortal.

I already did that but I still don't know what to do next.

Far east of Phantom Forest to get the rune, then enter Source Temple.

I got the rune but I still don't know where the source temple is

THe source TEmple is in the Center of the Wood. There ar many enemies, take me 5 Hours to kill them all!

THe you find deamons and the last king. Near the Kind is a stair up uns the rune there.

I am stuck in the first ara inside. there is an broken mirror on the rigth side and an wall in the North, how use the mirror, or how can I go past the blocking wall? (found the bloodstone near the mirror)
