The Noctuary (D&D 3.5e, Level 20+ Adventure)

[Burning Spear]

There is the charm domain you could take, to get it as a domain spell.
And Elysium, and Temptation, and Lust domains all give it as well.

Charm imo doesn't fit my fluff,
Elysium and Temptation are Prestige Domains if I'm correctly understanding it.
Hathor and Isis are both N.G. so Elysium could fit, but then I'd have to drop one of: Knowledge (can't), Family (loving the Domain Ability), Storm, Balance (don't want to drop) and Oracle (can't).

Lust seems by it's domain ability not to fit at all, 😆 a seductive mummy?! 😂
