I'm playing a Heretic of Nocticula (a particularly devout wizard, not a divine caster, so she's actually CG and not neutral) and, after butting heads with a party member who realized something was up, convinced him to help consecrate the shrine to Nocticula and Sarenrae (a dual-consecration as a show of good faith).
And while my PC is content with that, she doesn't want to just leave the place alone. Circumstances mean there wasn't any time to do more than hastily leave basic tenets behind, but after chapter 1 is over and there's some time she plans to return to the shrine and make spruce it up a bit, including leaving behind a shrine maiden to guide those who find it toward the Nocticulan Heresy rather than risk them stumbling into her demonic embrace.
The problem is...what do I use? My first thought was a homunculus but I didn't notice the clause about how they refuse to be more than a mile away from their master because it shuts down their telepathic link. I could, in theory, pay extra for better reception, but what are my other options?
It needs to be intelligent, effectively immortal, and willing to spend eternity in a room following a single command, which rules out...basically everything I could think of off the top of my head, ignoring GM fiat. Undead are either mindless or able to leave, outsiders don't stay bound for that long, most constructs with intelligence require someone to die and give up their soul, etc etc. So what would you all recommend?
While you're not wrong, the trick isn't in finding a way to get the GM to bend to my whims, it's in finding a fun, flavorful option that has enough basis in the RAW that I don't risk causing an aneurism when someone asks me "Why don't I just call up another one to do our chores?"
