Summoning & Turning Friendly NPCs - Creatures, Undead, Demons and Vampire Companions (followers)

I want permanent companions to fuel my vampire fantasy, who will follow me on adventures or guard my lair!

Turning Creature types! Wolves etc.

Necromancy - I would love to be able to create undead NPCs that can assist me. Lesser minions like Skeletons & Ghouls. More advanced and dangerous undead like Wraiths, Liches & Death-knights. Then at the top of this progression I could create a customisable vampire companion

Demonology - A spell school where I could summon or enthrall enemy demons, making temporary allies and eventually permanent minions. You could expand on this theme - Possessing NPCs and controlling them. Summoning demonic armour/weapons to boost stats, later create permanent equipable ones. Opening gateways to summon lesser demons or travel. Infernal Resilience, giving resistance to traditional vampire weaknesses like holy symbols or sunlight. Emit an aura that induces fear, weakness, or madness in nearby foes

And the ability to resurrect the advanced companions for both
