All the remains of Entropy is in Necromancy. Horror is the main "entropy" theme though for it.
Yep. One must remember that Theodosian Necromancy is not equal to Tamriellic Necromancy which I why I think some people see Necromancy in DAI as meh. Its not, it is just different.
Necromancy in Tamriel is about raising the dead, Mannimarco, Molag Bal, the undead and skeletons and ghosts, manipulation of death and disease...
Necromancy in Thedas is about spirit communion, mummification, treating the dead with respect, using lich powers to teach and to communicate...
Theodosian Necromancy is far more grey and benevolent as opposed to the typical Necromancy we see in fantasy games...
Also, Necromancy & Cassandra are related...Since she is from Nevarra and we learn Necromancy from a Mortalitasi...
